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)
Graph functions on this graph software.
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
