sin square theta + cos square theta = 1 How to prove?

Prove Sin^8 θ -Cos^8 θ = (Sin^2 θ - Cos^2 θ) (1 - 2 Sin^2 θ Cos^2 θ)

{1/(sec^2⁡𝜃−cos^2⁡𝜃)+1/(𝑐𝑜sec^2⁡𝜃−sin^2⁡𝜃)}sin^2⁡𝜃⋅cos^2⁡𝜃=(1 −sin^2⁡𝜃⋅cos^2⁡𝜃)/(2+sin^2⁡𝜃⋅cos^2⁡𝜃)

If sin theta + sin^2 theta = 1, find the value of cos^12 theta + 3cos^10 theta + 3cos^8 theta + cos
