Visual Calculus is a grapher to compute and graph limit, derivative, integral, 3D vector, partial derivative function, series, ODE etc.

Pre-calculus: functions, piecewise defined function, even and odd functions, polynomials, rational functions, composition of functions, trigonometric functions, exponential functions, inverse of functions, logarithms, parametric functions, polar coordinate graphs, solving equations

Feature Sample Note Functions can be in the form of explicit, parametric, piecewise, implicit and inequality Explicit form: y=x-x^3/6+x^5/120; y=x; y=x-x^3/6; y=sin(x) Parametric form: x=5cos(u)+3,y=3sin(u)+5; x=2cos(u)+1,y=2sin(u)-2 Piecewise form: y=x-1, if x<-1 y=-1, if x=-1 y=x+1, if x>-1 Implicit form: x^2-y^2-1=0 Inequality form: a-r<0 Cartesian and polar coordinate systems Cartesian coordinate system: y=x^2; y=1.5x+1 Polar coordinate system: r=10sin(2a) coordinate graph animation sin(x*y-t)<0 Graph of inverse function y=sin(x) and it's inverse function Even and odd functions y=sin(x) then let x'=-x Root y=(x-1)^2-2 Point of intersection(Solve equation) Area of intersectant field y=x^2-3, y=x+1
