abhi jee ka exam hai, wait a couple of days hah for people to respond xD

Split the 1 into cos^2 alpha +sin^2 alpha or cos^2 theta_r and sin^2 theta_r
depending on whichever one helps you most
If you need more help you could convert this into an integral using 2pir/n

i think you can do this by complex

I dont get this step
i wrote 1=cos^2(theta_r)+sin^2(theta_r)

limit n does not tend to infinity so ig we cant do this

They haven't specified n so that might lead to a simpler approach
(just an observation, haven't tried it in depth)
If anything you could create an inequality and use the sandwich theorem, that's another possible idea

Now
For the limits 0 and n-1 let the sum be S-
For the limits 1 and n let the sum be S+
those represent the upper and lower Riemann sums of the integral when 2pi r/n = x and 2pi /n = dx
and n tends to infinity

missed the summation symbol, my bad

Oh

Apparently I solved it by complex numbers

Nice
