Trigonometry mainly provides six functions for sine (sin), cosine (cos), and tangent (tan), also its reciprocal functions cosecant (csc), secant (sec), and cotangent (cot). These processes help in solving angle and distance related problems in both 2D and 3D surroundings.

The proper expression for the fixed-point iteration for the $n$th nonzero solution of $x=\tan\;x$ is $x_{k+1}=\arctan(x_k)+n\pi$.

To solve a trigonometric simplify the equation using trigonometric identities. Then, write the equation in a standard form, and isolate the variable using algebraic manipulation to solve for the variable. Use inverse trigonometric functions to find the …

In a right-angled triangle, the formula for the tangent function is expressed as the ratio of the perpendicular and base of the triangle. It can also be expressed as the reciprocal of the cotangent function. Mathematically, tan function is written as f (x) = tan x.

Tan (or tangent) is a trigonometric function. In a right-angled triangle, the tan of an angle x is defined as the ratio of the side opposite to the angle, to the side adjacent to the angle. $$tan\, x = {opposite \over adjacent}$$
