3. Here's a way to evaluate due to Euler. We've seen that sin 72 TZ - k² ·ÎI (¹-³). j=1 (a) Equate the coefficients of z² on both sides, to recover the desired sum. (b) Equate the coefficients of z4 on both sides to recover a different sum. By equating coefficients of higher powers of z, one can recover other identities too. On the next homework set we'll see a more general method to calculate sums.
