Question

Help me to find the product plz (opt math)

Answer 1

Answer:

$\left(sin\theta -cos\:a\right)\left(cos\:a+sin\theta \right)$

(sin(θ)-cos(a))(cos(a)+sin(0))

$\mathrm{Apply\:Difference\:of\:Two\:Squares\:Formula:\:}\left(a-b\right)\left(a+b\right)=a^2-b^2$

a=sin(θ),b=cos(a)

= sin²(θ)-cos²(a)
