Suppose x=4sin(theta, for theta (-pie/2, pie/2). Rewrite(sqrt16-x^2)^3/x^3

(Sorry Im not very good at making symbols. I hope you know what I mean here! if not I can try to rewrite it a different way)

x = 4sinθ

sinθ = x/4

so, the other side is √(16-x^2)

√(16-x^2)/x = cotθ

[√(16-x^2)/x]^3 = cot^3(θ)
