CALC - Trigonometric Functions

The standard trigonometric functions (sine, cosine, tangent, and the hyperbolic equivalents) take angle values expressed in radians. Large angles in excess of +/-2p may cause errors or return meaningless values.

The inverse functions (arc sine, arc cosine, and arc tangent) return angles in radians. The arguments must be in the range generated by the standard function to prevent errors. Return values are in the range (-p/2, p/2), except for @ATAN2, which returns a normalized angle in the proper quadrant (between -p and p), based on the signs of its two arguments.

The following functions are available:

@SIN(X)

sine of X

@SINH(X)

hyperbolic sine of X

@ASIN(X)

arc sine of X

 

 

@COS(X)

cosine of X

@COSH(X)

hyperbolic cosine of X

@ACOS(X)

arc cosine of X

 

 

@TAN(X)

tangent of X

@TANH(X)

hyperbolic tangent of X

@ATAN(X)

arc tangent of X

@ATAN2(X,Y)

normalized arc tangent of X/Y
