Calculus 1 Definition and 96 Threads

Ok so long story short, I need to enroll into a physics course that requires you to have taken Calculus 1. I am going to try and enroll, and hope that my enrollment office doesn't check my course history. ASSUMING hypothetically that I get the option to actually enroll and don't get denied...

So I started with limits and everything went well, and then into derivatives, and a problem started. First I know how to find the derivative of basic things using like ( limit definition of derivative) or (rules for derivatives) or ( product rule/ quotient rule/ chain rule)... My problem...

Homework Statement The problem is: f(x) = {ax^2 - b / (x - 2), x < 2 1/4(x^2) - 3c, x >= 2 If f is differentiable at x=2, what are the values of a, b, and c? In case it is hard to see, I have provided an image 2. Homework Equations I know that the limit definition of a...

Hi all, So I'm pretty devastated(and I'm to be blamed). I'm a first year cs and math major. So the thing is my math course is a full year course with 5 class tests and 2 finals(worth 2/3 of the final mark) Slacking off and poor time management gave me the privilege of failing all my class...

Hello Physics Forum, I am an aspiring civil engineer and I just stumbled across this website tonight. I am just now taking calc 2 and have pretty much started off on the wrong foot. This class is already a headache and we have just covered the first quarter of the class. I expect it to get...

Hi there, everyone! I'm sure this question has been asked many times before, but I did not really find any similar posts, so I hope you guys will bear with me! I am teaching myself what could be categorized as Calculus 1, using Adams' "Calculus: A Complete Course" along with "Schaum's 3000...

Homework Statement Lim ( 5+6x2)/(√(x3)) + 2x2 +1) x->∞ Homework Equations not allowed to use lhopitals rule The Attempt at a Solution first, i divided by x2, which yielded (5/(x2) + 6 + √(x)) / (2 + 1/x2 ) then i assumed that thelim x--> infi of 5/x2 = 0, lim x-->...

I'm hoping you guys/girls can give me some advice / techniques to getting a good grade in a 3.5 week summer calculus 1 course. I just finished the first week today, and there are about 3 more. There is a test each Friday, and I took the first one that was worth 12.5% today. I did bad. The...

Im having trouble starting the harder optimization problems in stewarts calculus (calculus 1). I noticed one of my major problems is not knowing how the picture of the optimized problem looks like. My test is only going to contain one optimization problem. So I am not worried about failing...

I am a math major and I need to take Methods of Discrete Mathematics. What is methods of discrete mathematics? Should I take it after My calculus series( including linear/ diff. equations)? Is it easy enough to take with Calculus 2? Thanks

I'm not entirely sure if this belongs in homework or elsewhere -- I'm self-teaching working through a basic calculus text, so it's not homework per se. In any case it's a simple differentiation problem wherein I am supposed to differentiate: f(x) = x(3x-9)^3 f'(x) = 3x(3)(3x-9)^2 Applying...

My question is what does Calculus 1 consist of in college (community college which is not that proof heavy). I have the Morris Kline book which I am self learning from and so far so good. I finally understood how vectors work in reference to an object m sliding down a slope which is...

Homework Statement An airplane flies at an altitude of 8 miles toward a point directly over an observer (see figure). The speed of the plane is 600 miles per hour. Find the rates at which the angle of elevation θ is changing when the angle is θ = 30°, θ = 60°, and θ = 80°. The Attempt...

Okay I had a calculus test and we got it back and I got this question wrong. I tried it again but I can't figure it out. The weight, w, in kg of an object is inversely proportional to the square of the distance, r, in km, from the center of the earth. Assume a stone of the ground has weight...

Hello, I've been around the forums before, but I finally decided to create an account to post things. :) I'm currently a sophomore in college majoring in physics. At my school physics 1 and calculus 1 are a co-requisite not a prerequisite, meaning I can take physics 1 and calculus 1...

I'm taking a short Calculus session this summer and the teacher zooms through things. I still don't fully understand differentials. I know that derivative give you the slope of a function at any point. And I know that dy is a small change in y and dx is a small change in x and how they can be...

So this summer I was planning to take calc 1 at a school, but they canceled it. Very aggravating. But I can take the course online somewhere, so will it hurt me later on to take it online? Also does anyone know of good accredited places that I could take calc 1? I was thinking BYU or I don't...

Homework Statement The Attempt at a Solution I figured out #11, could use help with the other questions. I have a final tomorrow in the morning and my professor gave us a few questions to try out so help would be appreciated. For #8 I'm not sure how to draw the second...

maybe I posted this in the wrong place. I signed up for an online university calculus course. I forgot most of algabra. Should I drop it and try to learn my stuff first? Can I learn it in 5 weeks? They give you about 6 months to complete the online course. I figure I can dedicate 15-20 hrs a...

Hello everyone, this is my first post so if I am doing something wrong let me know. My first year college calculus professor has slipped a little cookie into her syllabus that says the following. "Extra credit is a demonstration of excellence and mastery of skill taught in this course in a...

I'm currently taking Calculus with Analytical Geometry and I need to do some expedited review of the Trig and the algebra pertinent to the course. Does anyone have a definitive list of topics one should cover prior to learning calculus material? Any tips( P.S.- I want an "A" in this course)?

Hey, I am taking AP Calculus next year in High School. Is it the same thing as Calculus 1 for college? Reason why I ask I am looking to learn all of the material in advance.. Would this be a solid guide to follow -...

I am finally getting my feet wet, actually taking math courses that apply to my degree. Anyone have any suggestion what I should be studying before I take the class? I have borrowed a book from a local library called "Calculus Essentials for Dummies." I have a friend who is in calc 3, I...

Homework Statement I am given the problem "A function is defined by f(x) = 1-x^(2/3). a. find the minima and maxima of the function. State whether they are relative or absolute. b. graph the function." Homework Equations I found the derivative and set it equal to zero. y' =...

I go to a top 10 math school in the US and just received a B+ in Calculus 1 (the final was ridiculous!). Should I reconsider being a math major? I enjoyed the course considerably, but I feel that all math majors would breeze though it with an A. Any thoughts? Thanks.

Hi All: I am taking Calc 1 at a community college and we are using Calculus by James Stewart 7th edition. I am able to do homework problems that are assigned to us which are only a small subset of problems from end of the chapter exercises. However, we are not doing any of the remaining...

first time exposed to Calculus 1 and I'm not doing so well. I'm in the Mechanical Engineering major and I keep getting discouraged that maybe Engineering isn't the right choice for me. any suggestions?

Solve for b, f(x)=b^x Here is where I am so far lny=lnb^x lny=xlnb^x y'/y= lnb e^y'/y= e^lnb b= e^y'/y My question is, can I simplify the exponent y'/y any further, or is my answer good here? Thank you

Taken previously? Right now does a calculus 1 class , seem easy to you, compared to when you first took it? Usually when you take math classes they seems kind of daunting at first and then when you do math beyond that what seemed kind of perplexing at first becomes super easy? Opinions?

Homework Statement dy/dx=y-e-x Homework Equations none The Attempt at a Solution According to Wolfram Alpha the solution is y = cex+.5e-x . I tried multiple approaches, but I cannot obtain this answer. I can't figure out what step 1 is. I tried factoring out e-x from the right...

Homework Statement prove |arctan(x)-arctan(y)| \leq |x-y| The Attempt at a Solution I tried separating cases: 1. both x and y are in the same quadrant; 2. x and y are not in the same quadrant; 3. x and y are zero (trivial); 4. either x or y is zero. Now, i can see why each of these is...

Irrelevant context for anyone interested (feel free to skip this blue paragraph): I've always been a geeky, scientific nerd-type. But I've only been sort of a dilettante with all things science (i.e., well above the 50th percentile amongst my peers, but no area of expertise, by any means.)...

Homework Statement find \int\int_D sin\left(\frac{y}{x}\right)dA bounded by x=0, y=\pi, x=y^2The Attempt at a Solution I've only studied calculus 1, this problem is for my friend. I did read up briefly on double integrals however and this is why I'm stuck: From the limits and where the graphs...
