Prove that cos(x)tan(x) divided by cosec(x)^2 equals cos(x)^3 divided by cot(x)^3
Proof of trigonometric identity
fiind all solutions at interval [0,2pi] sin^2x - cos^2x = 0
(sin x + sin 3x + sin 5x )/ (cos x + cos 3x + cos 5x) = tan 3x
Suppose the θ is an acute angle and cosθ = 4/5. Using the results sin2x = 1/2*(1 - cos2x) and cos2x = 1/2*(1 + cos2x), find the exact values of cos1/2θ, sin1
