COS

Description: Returns the cosine of a number.

Syntax: COS(Number)

• Number is the angle in radians for which you want the cosine.

Remarks:

• If the angle is in degrees, multiply it by PI/180.

• When used in an event analysis flowchart, Number must evaluate to a numerical value. It can include:

• Numerical values

• Standard operands (+, -, *, /)

• Predefined mathematical functions (exp, log, sin, etc.)

• Event analysis internal functions

• Event analysis resources

• References to any ReliaSoft Workbooks

Example:

• COS(1.047) = 0.500171 [the cosine of 1.047 radians]
