Solving Trigonometric Equations By Finding All Solutions

WebThe Pythagorean Identities are based on the properties of a right triangle. cos2θ + sin2θ = 1. 1 + cot2θ = csc2θ. 1 + tan2θ = sec2θ. The even-odd identities relate the value of a trigonometric function at a given angle to the value of the function at the opposite angle. tan(− θ) = − tanθ. cot(− θ) = − cotθ. WebThe proof is that if you mirror the triangle on the 30 degrees side, you get a bigger triangle whose 3 sides are of the same length, and thus its angles are all 60.
