Examples:
Implicit graph: cos(X)=sin(Y)
Graph a parabola in Regular mode: X^2
Graph a circle in Parametric mode: cos(T);sin(T)
Set a variable: X=5
Use a variable: X+4: 9
Define a function: f(X)=X+1
Use a defined function: f(2): 3
Symbolic derivative: D(X,sin(X)): cos(X)

Notes:
-Swipe left for settings.
-Use semicolon (;) to separate functions in parametric relations.
