|TrigExpand[expr]||expand trigonometric expressions out into a sum of terms|
|TrigFactor[expr]||factor trigonometric expressions into products of terms|
|TrigFactorList[expr]||give terms and their exponents in a list|
|TrigReduce[expr]||reduce trigonometric expressions using multiple angles|
Functions for manipulating trigonometric expressions.
This expands out a trigonometric expression.
This factors the expression.
And this reduces the expression to a form that is linear in the trigonometric functions.
works on hyperbolic as well as circular functions.
automatically uses functions like Tan
whenever it can.
|TrigToExp[expr]||write trigonometric functions in terms of exponentials|
|ExpToTrig[expr]||write exponentials in terms of trigonometric functions|
Converting to and from exponentials.
writes trigonometric functions in terms of exponentials.
also works with hyperbolic functions.
does the reverse, getting rid of explicit complex numbers whenever possible.
deals with hyperbolic as well as circular functions.
You can also use ExpToTrig
on purely numerical expressions.
