Hello,
I am a beginner using Mathematica. I would like to know how to express for example a function that depends on three variables and to calculate it using a IF BLOCK.
I have the following function:
a(y,w,d)=(acos((w-y)/d)*d^2-sin(acos((w-y)/d))*(w-y)*d)
and I want to evaluate it, to evaluate this function I have to write a IF BLOCK like the following
IF (w-y)<d then
IF (w-y)>0 then
Gnuplot muss evaluate a(y,w,d)
else is pi*d^2
else cero.
I have attempt it. But only it works when I put a(y,w,d) if only depends on y, but it depends also from w and d.
Might anybody help me?
