The value of cot 0 - sin (90° - 0) cos(90° - 0) is​

How to remember the values of sin 60, sin 30, sin 45, etc?

Prove rightarrow sin (90^{o}-theta)cos (90^{o}-theta)=dfrac {tan theta}{1+tan ^{2}theta}

If xsin(90^° theta) cot(90^° theta) = cos(90^° theta), then x is equal to 1. 0 2. 1 3. 1 3. 2

cos(90−θ)sec(90−θ)tanθ/cosec (90−θ)sin(90−θ)cot(90−θ)+tan(90−θ)/cotθ.
