Topic: adding parametric graphs
How can add two parametric functions?
e.g.:
x(t)=2*t, y(t)=t^2 plus x(t)=t^2, y(t)= t^4

Select Function|Insert function in the menu, choose Parametric function as Function type and enter your first function in the fields for x(t) and y(t). Repeat for the second function.

What I meant is to plot the sum of the two functions.
e.g.:
function "sum" in example.pdf (attachment). Y1 and y2 are parametric function (Y1: x(t)=(2*10^5*t+t^2)^0,5, y(t)=COS(2*PI*t) and Y2: x(t)=(2*10^5*t+t^2)^0,5-90, y(t)=COS(2*PI*t) ). SUM has to be the sum of y1(t)+y2(t) for the same x(t) values.

Re: adding parametric graphs
You will have to calculate that yourself. If you take your original example you get:
x(t)=2t, y(t)=t^2 => f1(x)=(0.5x)^2
x(t)=t^2, y(t)=t^4 => f2(x)=x^2
f(x)=f1(x)+f2(x)=(0.5x)^2 + x^2 = 1.25x^2
