Question

prove that 1 / sin square A×cos square A-sin square A/Cos square A - cos square A/ sin square A=2(sin square A+ cos square A)​

Answer 1

Answer:

$\huge\pink{\boxed{\green {\mathbb{\overbrace {\underbrace{\fcolorbox{red}{aqua}{\underline{\pink{ur\: answer }}}}}}}}}$

Sin A + sin(square) A=1

Sin A =1- sin(square) A . (1)

By identity

sin(square) A+cos(square) A=1

1-sin(square) A=cos(square) A

On putting this value in (1)

Sin A= cos (square) A

On squaring

Sin (square) A= cos (raised to 4) A. (2)

We have to find

Cos (square) A+cos ( power 4)

Cos(square) A + sin(square)A From(2)

=1 . by identity
