RAPTOR Trigonometric Functions

We can use trigonometric functions in Raptor flowcharts. Some functions are sin, cos, tan, arcsin, arccos, arctan, etc. The argument for the functions should be in radians. The trigonometric function argument in RAPTOR uses radians, so if you have an angle in degrees, you must convert it to radians.

 

Trigonometric Functions

The functions accept one argument, the angle in radians.

RAPTOR Trigonometric Functions	Syntax	Description
sin	sin(angle_in_radians)	The sin function returns the sine of the angle provided in radians. For example: sin(PI/2) returns 1.
cos	cos(angle_in_radians)	The cos function returns the cosine of the angle provided in radians. For example: cos(0) returns 1
tan	tan(angle_in_radians)	The tan function returns the tangent of the angle provided in radians. For example: tan(PI/4) returns 1.
arcsin	arcsin(value)	The arcsin function returns the angle whose sine is the specified value. The result is given in radians.
arccos	arccos(value)	The arccos function returns the angle whose cosine is the specified value.
arctan	arctan(value)	The arctan function returns the angle whose tangent is the specified value.

 

 

RAPTOR also supports inverse hyperbolic functions like:

• arcsinh(x)
• arccosh(x)
• arctanh(x)

Examples

Let’s look at the function usage with examples. You can invoke the functions in the Output symbol to view the function output.

sin(x)

x should be in radians.

cos(x)

Sometimes, if you calculate the functions in degrees. In that case, you need to convert the degrees into radians.

xDegrees = 60

x= xDegrees*pi/180

 

tan(x)
