COS

Numeric Fun ction

SYNTAX: n = COS(m)

PURPOSE: To return the trigonometric cosine function.

REMARK S: m must be in radians. To conver t from degrees to radians, multiply by PI/180 where P I =

3.141593.

Trigonometr ic functions ar e computed as a power ser ies in CA MBASIC. Calculations are done in

single precision floating point to seven digits of precision. Since the power series is an

approximation, the result will be accurate to four to six digits, depending upon the value of m.

RELATED: ATN, SIN, TAN

EXAMPLE: 10 PI = 3.141593

20 PRINT COS(PI)

30 DEGREES = 180

40 RADIANS = DEGREES * PI/180

50 PRINT COS(RADIANS)

RUN
