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 |
inverse cosine (arccosine) | >arccos( ); | See sine function |
inverse tangent (arctangent) | >arctan( ); | See sine function |
