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. WebSin3x. Sin3x gives the value of the sine trigonometric function for triple angle. On the other hand, sin^3x is the whole cube of the sine function. Sin3x is a triple angle identity in trigonometry. The expansion of sin3x formula can be derived using the angle addition identity of the sine function and it involves the term sin^3x (sin cube x).
