If cosec A = 2, find the value of 1/tan A + sin A/1+ cos A

WebExpert Answer. 1st step. All steps. Final answer. Step 1/1. We can start by using the identity: sin^2 A + cos^2 A = 1. Substituting the given value of cos A into the identity, we get: View the full answer. WebFor tan 45 degrees, the angle 45° lies between 0° and 90° (First Quadrant ). Since tangent function is positive in the first quadrant, thus tan 45° value = 1. Since the tangent function is a periodic function, we can represent tan 45° as, tan 45 degrees = tan (45° + n × 180°), n ∈ Z. ⇒ tan 45° = tan 225° = tan 405°, and so on.
