Hello!

I am having problems with my maths here.

I need a function f(index) that for my index going from 0 to 100 (so it's:
0,1,2,3,4...99,100) returns the values between 0.5 and 5 for index between
0 and 50 and then between 5 and 0.5 back again for index between 50 and
100.

So the return value goes for example 0.5, 0.7, 1, 1.3...5, 4.8,4.2....0.5

Thank you very much!

Greetings,

Chrisir
