WebProving Trigonometric Identities - Basic. Trigonometric identities are equalities involving trigonometric functions. An example of a trigonometric identity is. \sin^2 \theta + \cos^2 \theta = 1. sin2 θ+cos2 θ = 1. In order to prove trigonometric identities, we generally use other known identities such as Pythagorean identities. WebAll steps. Final answer. Step 1/3. In the 4th quadrant only cos θ and sec θ are positive, rest all trignometric functions are negative. Given cos θ = 3 5. We also know that in a triangle ABC. cos θ = base hypotenuse = B C A C. In our question, A C = 5 and B C = 3. So by Pythagoras theorem.
