Prove sin(x) × cos(x) × tan(x) = 1 - cos2(x)

Here is the step by step demonstrations to prove sin(x) × cos(x) × tan(x) = 1 - cos2(x) trig identity easily.


Sin(x) × cos(x) × tan(x) = 1 - cos2(x) - Trig Identities Proof

LHS
= sin(x) × cos(x) × tan(x)

= sin(x) × cos(x) ×
sin(x)

cos(x)

= sin2(x)

= 1 - cos2(x)

= RHS

Hence Proved.
