Answer 1

Answer:

sin theta + cos theta = √ 2 cos theta

sin (90- theta) = cos theta

sin theta = cos (√2-1)

sin / cos =√2-1

tan theta= √2-1

cot theta = 1/√2-1

= after rationalising

= √ 2+1

Answer 2

Answer:

$\sin( \infty ) + \cos( \infty ) = \sqrt{2} \cos( \infty ) \\ \sin( \infty ) = \cos( \infty ) ( \sqrt{2} - 1) \\ \frac{ \sin( \infty ) }{ \cos( \infty ) } = \sqrt{2} - 1 \\ \tan( \infty ) = \sqrt{2} - 1$

$\cot( \infty ) = \frac{1}{ \sqrt{2} - 1 } \\ \cot( \infty ) = \frac{1}{ \sqrt{2} - 1 } \times \frac{ \sqrt{2} + 1}{ \sqrt{2} + 1} \\ \cot( \infty ) = \sqrt{2} + 1$

Hope it helps you friend. ✌
