why is it so difficult to graph a 3 dimensional vector on any bloody calculator? I can't even seem to find the right format to graph a x-y-z vector on my new imac grapher software. does anybody know how to graph a vector on a cartesian coordinate system using a texas instrument calculator...

Hi! For those of you who know how to use Matlab, I want to graph two functions f = \frac{(2+x)}{(x-2)(x+1)} and g = \frac{1}{\sqrt{(2x^2 - 1)(x^2-1)}} On my instructions sheet it says; draw f and g on the same grid on a "suitable" domain. The domain of f is all the real numbers except...

I remember using this program called "Carbi-Geometry" or at least I think that was the name. I googled for it today and it's not free "anymore" unless I'm confusing the name. I want to be able to graph not only triangles, but graphs as well, and I need to be able to label things. Thanks!

Hi For higher mathematics i need the highest featured calculator and since graphing calculators are generally expensive (at least for me) so that's why I'm investing some time in researching Online b4 I buy so that i can shell money only once to buy a graphing calculator which is so powerful in...

I'm trying to find patterns for polar curves. I just reviewed and feel comfortable with taking advantage of symmetry, but I still have trouble with some type of curves. Limacons: Two types 1) inner loop 2) no inner loop Is there a general formula that tells me whether there will be an...

Hello I plan on applying to the university of waterloo next year and due to the fact that many of my marks are not that great (failed gr 10 math) I decided to start a site to showcase my ability in math and programing. For those of you who are interested I wrote a program to graph regions of...

This isn't really a homework problem. I'm studdying for the AP Physics C: mechanics test by working on practice free response problems that my teacher gave me. My question pertains to a problem in the 1993 set of questions. Let's say, for example, a car moves to the right with a constant...

Homework Statement I'm having difficulty graphing with respect to y (unless I graph it point by point). For example, I find it hard to graph: f(y)= \frac{y}{\sqrt{16-y^2}} Does anyone know of an easy method to graph such a function or know how to do it on a Ti 84+ SE? Also, it would...

I'm having a bit of a problem with choosing a calculator, I am taking algebra 2 and Honors Chem and plan to take calculus AP Chem and Physics next year. The teachers have stopped supplying the TI-83s and I need to know what to invest in. My dad has insited I go with the HP 50g as he is an...

Wasn't sure which section this should be in, so please move if inappropriate. If a plot between two variables theoretically should pass through the origin, should you force the linear regression through the origin. I seem to get a much better value for my gradient when forced through the origin...

Below is some code that creates a semi-transparent cylinder. firstcylinder = ParametricPlot3D[{Cos[t], u, Sin[t]}, {t, 0, 2 Pi}, {u, -2, 2} , PlotStyle -> {Red, Opacity -> .3}, Mesh -> None]; Show[firstcylinder] Draw a second cylinder that is perpendicular to the given cylinder. Draw a...

Hi, I am graphing a hyperbola and have completed everything, except I am not to sure how to draw the final curve in. I have the center, foci, vertices, and axis'. I cannot seem to find any information on actually plotting the curve in. Am I supposed to freehand it in from the vertice and follow...

Question asked to find the units of k after you find the porpotionality statement i ended up getting t\propto\frac{\sqrt{h}}{d^2} so i turned that into an equation and end up with t=k\frac{\sqrt{h}}{d^2} solved for and found it on average to be 30 now the question is asking what the...

Graphing a function on a given interval...?? My problem is: Use a graphing calculator to graph the function...? ...over the given interval f(x)= -x^4+3x^3-4x+3 (-2,3). How do you graph something on a specific interval? P.S. I have the Casio fx-9750G PLUS graphing calculator.

I am taking a vector calculus course and am having trouble figuring out how to graph things in Matlab to verify my answers. Here is exactly what I want to do: I want to graph side by side two different graphs simultaneously, so I can compare them. I will give you the equations of the two...

Can anybody explain the process to use when graphing algorithmic functions? Sorry if this is a stupid question to ask, but I have a textbook that doesn't explain the process completely. I'm trying to nail these concepts down, but I guess I'm pretty much hopeless when it comes to math. I...

Homework Statement While Cruising along a dark stretch of highway with the cruise control set at 25 m/s, you see, at the fringes of your headlights, that a bridge has been washed out. You apply the brakes and come to a stop in 4.0s. Assume the clock starts the instant you hit the brakes...

I want to graph curves in C++. I can program them in, find the x,y,z coordinates, but I don't know how to graph them. I am using Dev C++. How would I go about graphing them? Is there some predefined graphics library that I can use or is it more complicated than that?

I'm writing a program in VB but since math isn't my strongest suit I'm having a little trouble figuring out the equation for this: I have a grid 100 x 100. The user will input the direction in deg and the distance to travel. I need to get the destination grid x and Y. 0 Deg is facing up...

I'm about to buy a graphing calculator, and I don't know whether to get the Texas Instruments TI-84 (Silver Edition), or the Casio CFX9850GC+ (which has the added frivolity of a colour screen). I can't get the TI-89, because it has algebra software built in, and so I'm not allowed to use it...

x+|x|=y+|y| so for x which in a sense will be the same for y x if x > 0 -x if x < 0 now does that only apply to my absolute x? or does it apply to both x and |x|?

I'm really unsure how to go about graphing a complex function. Like, f(z) = z^2, where z = x+iy. This ISN'T a homework problem, but I'm studying for an exam and that's an example in a book I'm reading and it says "the image of this function" and goes on explaining some things relevant to...

Hello everyone, I use a TI-83 Plus and I'd like to know if there is a quick way to convert an angle from radian to degree and vice versa. I am not referring to multiplying by (pi/180) or (180/pi). Thanks!

Homework Statement Why did we choose to linearize our data by plotting velocity versus time rather than by distance versus time-squared. Use d-v-a-t (distance=velocity*time+0.5*acceleartion*time-squared) equations to present a convincing answer. Homework Equations 1. d=vt+1/2at^2 2...

Homework Statement My goal is to create a graph in excel that moves as I hold the F9 key(and progressing the time). The concept is of a 'rubber ball' bouncing after it is dropped from an initial height. The variables that must be left in separate cells (to easily change) are kinetic energy...

Hi Im trying to find the elastic potential energy stored in a mousetrap spring. I plan on doing this by graphing the spring's constant then integrating the function. I just wanted to know what i should be measuring with the x-axis. In normal springs the force is on the y-axis and the...

I really don't like Excel for graphing for several reasons. The main issue is that it only has uniform uncertainties for all data points and you cannot put different uncertainties for different data points. I also just don't feel the graph looks good quality at all. People I have asked...

Homework Statement I would like to graph the position, velocity, and acceleration curves (over time) of an object that is launched straight up from the surface of the Earth, but I need to take into account the fact that the Earth's gravitational pull weakens as the object gets higher. The...

hey. i want to graph a projectile motion. i got the code of a sine wave but the x and y axis' are in the opposite sides. i want the curve to look like a projectile with the curve facing down. thanx. here's my code #include <iostream.h> #include <iomanip.h> #include <math.h> #include...

Does anyone have any idea why applied force is plotted on the vertical axis of the graph even though it is an independant variable?

Hey. i am having a problem graphing a projectile motion into C++. At the moment I am using the program Microsoft Visual C++ at uni. i got a problem here that i can't even start to solve. Well the problem asks me to to ask the user to enter the intial velocity and the angle at which the...
