Hello,
I am new to this forum and I apologise if I have placed this question in the wrong place and will move it if needed. I have a formula that is written as f(x) = A*cos((2*pi*x)/T) , A being Amplitude of the Cosine wave and T being the period. when I put this into a sketching program the function preforms how I presume it should. The Question I have is that I would like to calculate the length of the wave between 2 points and I presumed this would use the integral method, how ever it's been a very long time since I've done any sort of math and it didn't work how I thought it would.
I inputted ∫ 10 , 0 10*cos((2*pi*x)/10)
as an example and got an answer of
100*cos((x*pi)/5) which is not what I was expecting.
If anyone would be able to help me in the right direction it would be really appreciated, I am sure I am just missing some information along the way.
Thankyou
