I am wondering if there is a way to alter the way inverse functions are rendered in the question?

For example, inverse tan is rendered as $\tan^{-1}(x)$ in the question text. To keep notation consistent with the rest of the subject, I am hoping to render it as $\arctan(x)$.

I recall seeing a similar post previously, but have been unable to locate it. Any directions would be appreciated.

I've attached a small example of the type of problem I am trying to create below.

Thank you very much

Regards,

Thomas

## 1/(1+y^2)exp(arctan(y))

## 1/sqrt(1+y^2)*exp(arcsinh(y))
