Expressing Everything with the Product of Secant and Cosecant

0:00 Introduction
0:41 (secθ)^2+(cscθ)^2
1:44 secθ+cscθ
3:54 (secθ)^3+(cscθ)^3
It's trigonometry time again, and today's problem is actually quite interesting. Here, the product of secant and cosecant is given as k. Using your knowledge of polynomial expansion and factorization, you must express several sums of powers of secant and cosecant in terms of k.
