Question

Ten tiata =? Cos tetai

Answer 1

Answer:

$\tan( \theta) = \sin( \theta) \\ \frac{ \sin( \theta) }{ \cos( \theta) } = \sin( \theta ) \\ \sin( \theta) ( \frac{1}{ \cos( \theta) } - 1 ) = 0 \\ \sin( \theta) = 1 \: \: \: \: and \: \cos( \theta) = 1 \\ \theta = (4n + 1) \frac{\pi}{2} \: \: and \: \: \theta = 2n\pi$

Answer 2

Answer:

tan A=sin A ÷cos A

if this is not the answer u want plz comment and let me know
