Question

( cosecTheta - cot theta)² = 1-cos theta / 1+ cos theta

Answer 1

Here we use the formula " tan theta is equals to square root of 1 - cos theta by 1 + cos theta in the last step.

Hope It Helps..!

Answer 2

Step-by-step explanation:

LHS=

${1 \div \sin(theta) - \cos(theta) \div \sin(theta) } ^{2} \\ (1 - \cos(theta) \div \sin(theta) ^{2} \\ (1 - \cos(theta)^{2} \div \sin ^{2} (theta) \\ 1 - \cos(theta) \times 1 - \cos(theta) \div 1 - \cos {}^{2} (theta) \\ 1 - \cos(theta) \times 1 - \cos(theta) \div (1 + \cos(theta) ) \times (1 + \cos(theta) ) \\ 1 - \cos(theta) \div 1 + \cos(theta)$
