7 Fundamental Trigonometric Identities | gkmcqs19.blogspot.com 7 Fundamental Trigonometric Identities Trigonometric identities are equations involving trigonometric functions that are true for all values of the variables involved. These identities are essential tools in mathematics, physics, and engineering. Here, we focus on 7 fundamental trigonometric identities that form the basis of trigonometry. 1. Pythagorean Identity sin 2 (θ) + cos 2 (θ) = 1 This is the most fundamental Pythagorean identity, derived from the Pythagorean theorem. From this, two additional Pythagorean identities can be derived, but this is the primary identity. 2. and 3. Quotient Identities tan(θ) = sin(θ) / cos(θ) cot(θ) = cos(θ) / sin(θ) These identities define the tangent and cotangent functions in terms of sine and cosine. 4., 5., 6., and 7. Reciprocal Identities cs...
