Trigonometric functions

   

Input(s)

 

acos(X)

Returns the arccos (inverse cosine) of X. Result is in radians.

   

asin(X)

Returns the arcsine of X. Result is in radians.

   

atan(X)

Returns a value in radians (range -pi/2 to pi/2), being the arctangent of X (the ratio of two sides of a right triangle). Same as arctan(X).

   

atan2(X,Y)

Returns the arctangent of X. Result is in radians.

numeric,numeric

 

cos(X)

Returns the cosine of X (an angle in radians)

   

cosh(X)

Hyperbolic cosine of X.

   

hypot(X,Y)

Returns length of hypotenuse of triangle with base X and height Y

numeric, numeric

 

sin(X)

Returns the sine of the argument (an angle in radians)

   

sinh(X)

Hyperbolic sine of X.

   

tan(X)

Returns the tan of the argument (an angle in radians)

   

tanh(X)

Hyperbolic tangent of X.
