In trigonometry, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined. Geometrically, these are identities involving certain functions of one or more angles.

In the given question, we need to prove `1 + cot^2 theta/(1 + cosec theta) = cosec theta` Using `cot theta = cos theta/sin theta` and `cosec theta = 1/sin theta` We get `1 + cot^2 theta/(1 + cosec theta) = (1 = cosec theta + cot^2 theta)/(1 + cosec theta)`
