Question

sin theta - cos theta = 0 find the value of sin theta + cos theta is

Answer 1

Answer:

$\sqrt{2}$

Step-by-step explanation:

$sin( \alpha ) - \cos( \alpha ) = 0$

$\sin( \alpha ) = \cos( \alpha )$

$\tan( \alpha ) = 45 ^{o}$

$there \: fore$

$\sin( \alpha ) + \cos( \alpha ) = \sin(45) - \cos(45 ) = \frac{1}{ \sqrt{2} } + \frac{1}{ \sqrt{2} } = \frac{2}{ \sqrt{2} } = \sqrt{2}$
