Sec, Cosec and Cot – Mathematics A-Level Revision

Webfunctions are derived in some way from sine and cosine. The tangent of x is deﬁned to be its sine divided by its cosine: tanx = sinx cosx: The cotangent of x is deﬁned to be the cosine of x divided by the sine of x: cotx = cosx sinx: The secant of x is 1 divided by the cosine of x: secx = 1 cosx; and the cosecant of x is deﬁned to be 1 ... WebWe know that the addition formula for sin is given as: \(Sin (X + Y) = Sin X Cos Y + Cos X Sin Y,\) Where X and Y are the two angles. In the above formula replace Y by X, with the assumption that both angles X and Y are equal. Thus, \(Sin (X+X) = Sin X Cos X + Cos X Sin Y\) Hence Sin 2x = 2 Sin x Cos x. Solved Examples for Sin 2x Formula WebThree examples are that (1) any trigonometric expression can be converted to an expression in terms of only sin and cos, (2) expressions involving exp(x) can be converted to their hyperbolic forms, and (3) a trigonometric function with an argument of the form q ⁢ π, where q is a rational, can in some cases be converted to radical form. harissa stew
