I tried to find the length of a sine curve using calculus.I got stuck in the integral of integral(sqrt(cos(x)^2+1), x, 0, a). Limits are from 0 to point a,i.e. length of curve from 0 to any point a.With some approximations I found out the length of sine curve as a result.I have attached the derivation of my result.I tried searching books and internet for this result.But couldn't find like this one.It also seems that this result gives more precise answer.
