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...

Hi everyone, I am trying to get an intuitive grasp of the Euler Relationship e^i(theta)=cos(theta)+i sin(theta) and also understand how to graph the exponential spiral, as demonstrated on this web page: http://www-math.mit.edu/daimp/ComplexExponential.html" Ok, first the neuron...

Hi all, Right now I am doing some Diff equations homework but am having difficulty with a problem. The problem asks me to draw a direction field for the system x' = \left(\begin{array}{cc}1 & 1\\4 & 1\end{array}\right)\left(\begin{array}{cc}x_1\\x_2\end{array}\right) The proper...

How would you graph y=f(x)-4? I am not sure how the original graph looks like y=f(x) either. Also, if i were to graph this using a graphing calculator, how would that be done?

I was trying to build a program that let's you find the integral and shows you the curve after giving you the solution. And I don't know how to write the code for the calculator to ask you for the y value. I know how to use drawf but you can't set your zoom to zoomfit because your calculator...

Hi all, Just wanted to note that we created an online graphing calculator: http://fooplot.com/ which should work in most modern browsers (except Safari). Hope you find it useful - share it, let us know if you find it useful, see any bugs, or have any suggestions about what would be useful...

Does anyone know where I can find free 3-Dimensional Graphing software that can graph spherical coordinates (i.e. \rho=f(\theta, \phi ))?

Hi all, found this forum while looking for a solution to this problem: When I graph a y1=sin(x) I get the sin wave you would expect. but... When I graph y2=5+4*sin(pi/12)(x+10) I get a line instead of a wave? What gives? I'm in radian, I reset my factory defaults... Am I entering...

I have a TI-83 graphing calculator and am thinking about upgrading to the 89 because extra useful features. Is it worth it?

hey all if I have the function for a derivative (which it is impossible to find an integral for, by the way), how do I graph the original? This graph is shaped kind of like an M, meaning it has some sharp points...on the original graph, would these be asymptotes or also sharp points?? thanx...

Help me decide. I want something that can help w/ calculus,trig,physics,statistics(not an absolutely necessary feature) and chem(not sure what features would be added to help this, but if you know then do tell) and allowed on SAT/ACT. any ideas

Hi, I was looking for some Windows software that did the job a graphing calculator does, but on the computer screen. I've been using the calculator that comes with Microsoft Student, but it lacks some features that would be quite useful (specially when it comes to complex functions). Which...

Hi, I've a basic knowledge of c++, but I've never learned graphing. What little I know, I've picked up myself. I am trying to graph the motion of a projectile launched with a given speed and at a given angle, but the graph doesn't complete. Also, its very spaced out. I know its a parabola so I...

I know how to use Excel for accounting stuff, but it's a nightmare for graphs. Is there some shareware I could use? What do most people use?

what would a wave function of phi(x) = Ke^(-a|x|) look like? would it be like an exponential graph with a graph reflected along the y axis? and its probability distrubution (phi)^2? i have no idea...i can't seem to find it by googling.

If the end of a string is given a single shake, a wave pulse propagates down the string. A particular wave pulse is described by the function y(x,t) = (A^3/(A^2 + (x - vt)^2)) where A = 1.00 cm, and v = 20.0 m/s. a) Sketch the pulse as a function of x at t = 0. How far along the string...

For my time series and spectral analysis class i need to graph something like in the attachment. i need to have 100 numbers that are connected like that, and then 'add' them to a sinusiodal wave to create a real life wave - with noise. How would i do this using mathematica?? I can easily...

Hey Guys, In PreCalculus, today, I received a fairly difficult project -- probably not as hard as you would think, but I do need help. We are asked to create one picture on our Graphing Calculators. I have done about 11 so far, but none are as I like them. This is what I put into the Y...

I’m having trouble graphing this equation: 16x^2+9y^2=144 I have entered it into both my Algebrator program and the quickmath.com website. They both gave the same graph of the ellipse. In each case the major axis was vertical. With the Algebrator program it simplifies the above equation...

If I am using the Plot3D command in Mathematica, how can I plot two separate functions on the same coordinates? Specifically, I am trying to get a picture of the intersection of x+y+z=1$ with x^{2}+y^{2}+z^{2}=1.
