convert/csccot converts all trigonometric functions appearing in the expression to csc and cot, and converts all hyperbolic functions to csch and coth.

If the optional parameter x is specified, then only those functions that depend on the variables in x will be converted.

$\mathrm{convert}\left(\cos \left(x\right)\,\mathrm{csccot}\right)$

$\frac{\cot \left(x\right)}{\csc \left(x\right)}$

$\mathrm{convert}\left(\mathrm{sech}\left(x\right)\,\mathrm{csccot}\right)$

$\frac{\mathrm{csch}\left(x\right)}{\coth \left(x\right)}$

$\mathrm{convert}\left(\tan \left(\tan \left(x\right)\mathrm{sech}\left(a\right)\right)\cos \left(b\right)\,\mathrm{csccot}\,\left\{b\,x\right\}\right)$

$\frac{\cot \left(b\right)}{\cot \left(\frac{\mathrm{sech}\left(a\right)}{\cot \left(x\right)}\right)\csc \left(b\right)}$
