Add this app to your lists
With MathGrapher, you can visualize function equations, parametric equations, and/or polar equations. You can also animate an equation by defining the range of one or more parameters: a, b, c, or d.

Here are some examples:

Function equation:
y = a*x^2 + b*x + c

y = log(2,x)

Parametric equation:
x = a*sin(t); y = b*cos(t)

Polar equation:
r = a*cos(b*t + pi/2)

You can select equations from the equation gallery that contains some predefined equations.

You can save the equations for later use.

    I like it very much, but when I edit an expression,instead of inserting or changing in the middle of the text,deleting all and typing again. can you fix it? Thank you very much:3

    This is a powerful and simple grapher, and lets you graph most if not all of functions and parametric equations that you want to see. Although your equations must be functions, and the way you change any function after creating it can be cumbersome, it's still a great tool, and does what it needs to do.
