Thank you for the reply, I am obviously doing something wrong between;
cos5x=0
and
5x= π/2 or 3π/2 ( i understand where you get 3π/2, just another revolution from π/2)
what i don't understand is how you got π/2, I was under the impression that you take the inverse of cosine from each side of...
Homework Statement
f(x) = sin5x ; [π/5,2π/5] finding the point c which f'(x) =0. I understand the theorem and how to complete it, my issue is using the triq functions
Homework Equations

my answer is not correct, I am...
Hello all!
I am new here on Physics Forums, I am returning to school and plan to major in Mathematics. I spent ten years in the US military and was a horrible student, nevertheless I am exciting about my upcoming challenge and sure I'll be posting questions here shortly.
