Notation. Several notations for the inverse trigonometric functions exist. The most common convention is to name inverse trigonometric functions using an arc- prefix: arcsin(x), arccos(x), arctan(x), etc. (This convention is used throughout this article.) This notation arises from the following geometric relationships: [citation needed] when measuring in radians, an angle of θ …

sin(x) = sqrt(1-cos(x)^2) = tan(x)/sqrt(1+tan(x)^2) = 1/sqrt(1+cot(x)^2) cos(x) = sqrt(1- sin(x)^2) = 1/sqrt(1+tan(x)^2) = cot(x)/sqrt(1+cot(x)^2) tan(x) = sin(x

Inverse cosine function. The arccosine of x is defined as the inverse cosine function of x when -1≤x≤1.. When the cosine of y is equal to x: cos y = x. Then the arccosine of x is equal to the inverse cosine function of x, which is equal to y: The values of sin, cos, tan, cot at the angles of 0°, 30°, 60°, 90°, 120°, 135°, 150°, 180°, 210°, 225°, 240°, 270°, 300°, 315°, 330°, 360° Arccos(x) function.

When the cosine of y is equal to x: 3. Complex number Analysis : (a) Naturally, we like to begin with z = cos 10° + i sin 10° and obviously we have to use de Moivres’ theorem, since z3 = cos 30° + i sin 30° , z5 = cos 50° + i sin 50° , z7 = cos 70° + i sin 70°. (b) During the calculation in part (b) below, we find that it is rather difficult to simplify. We therefore need Trigonometric Identities Pythagoras’s theorem sin2 + cos2 = 1 (1) 1 + cot2 = cosec2 (2) tan2 + 1 = sec2 (3) Note that (2) = (1)=sin 2 and (3) = (1)=cos .
