The convert(expr, 'expsincos') calling sequence converts all trigonometric functions appearing in the expression to sin and cos, and converts all hyperbolic trigonometric functions to exponential form. For example, $\tan \left(s\right)$ is replaced by sin(s)/cos(s).

If the optional variable x, which can be a name or a list or set of names, is specified, then only those expressions that depend (in the sense of the procedure depends) on x are affected.

$\mathrm{convert}\left(\cot \left(x\right)\,'\mathrm{expsincos}'\right)$

$\frac{\cos \left(x\right)}{\sin \left(x\right)}$

$\mathrm{convert}\left(\sinh \left(x\right)\,'\mathrm{expsincos}'\right)$

$\frac{{\ⅇ}^x}{2}-\frac{1}{2{\ⅇ}^x}$

$\mathrm{convert}\left(\tan \left(s\right)+\sec \left(t\right)\,'\mathrm{expsincos}'\right)$

$\frac{\sin \left(s\right)}{\cos \left(s\right)}+\frac{1}{\cos \left(t\right)}$

$\mathrm{convert}\left(\tan \left(s\right)+\sec \left(t\right)\,'\mathrm{expsincos}'\,s\right)$

$\frac{\sin \left(s\right)}{\cos \left(s\right)}+\sec \left(t\right)$
