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.

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...

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?

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!

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.

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).

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...

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?
