Question

if teetha= 45°, then find the value of 1-cos 2 teetha / sin 2 teetha.​

Answer 1

Step-by-step explanation:

$(\Theta) = 45 \\ \\ So, \: \: (2 \Theta) = 90 \\ \\ \\ \sin(2 \Theta) = \sin(90) = 1 \\ \\ cos(2 \Theta) = cos(90) = 0 \\ \\ \therefore \: \: \: \frac{1- \cos(2 \Theta)}{\sin( 2 \Theta)} \\ \\ \frac{ 1 - 0}{1} \\ \\ \boxed{ \implies 1}$
