Constants, Functions and Measurements used in Thread Measurement PDF

Function: arcsec, arcsec(x)
Inverse trigonometric secant – Unary function.
Function: cos, cos(Angle)
Cosine of an angle is the ratio of the side adjacent to the angle to the hypotenuse of the triangle.
Function: cosec, cosec(Angle)
The cosecant function is a trigonometric function that is the reciprocal of the sine function.
Function: cot, cot(Angle)
Cotangent is a trigonometric function that is defined as the ratio of the adjacent side to the opposite side in a right triangle.
Function: sec, sec(Angle)
Secant is a trigonometric function that is defined ratio of the hypotenuse to the shorter side adjacent to an acute angle (in a right-angled triangle); the reciprocal of a cosine.
Function: tan, tan(Angle)
The tangent of an angle is a trigonometric ratio of the length of the side opposite an angle to the length of the side adjacent to an angle in a right triangle.
