FUNCTION	SYNTAX	ANNOTATED EXAMPLE
square root	>sqrt( );	>sqrt( x – 2 ); computes .
	OR > ( )^(1/2);	>(x-2)^(1/2); computes .
any root	>surd( x, n);	Input >readlib(surd): then input >surd( -8, 3)  to compute the real cube root of -8.  The command readlib(surd): need onlv be excuted  once in a session.
exponential function	>exp( );	>exp(x^2); computes
natural logarithm	>ln( );	>ln(3/x); computes natural logarithm of 3/x
sine function	> sin( );	>sin(3*Pi/4); computes
cosine function	> cos( );	See sine function
tangent function	>tan( );	See sine function
inverse sin (arcsine)	>arcsin( );	See sine function
