I also believe what Myles_Zadok said about that " it is simplifying the expression to what it believes is the simplest form"

]]>There is probably a way though. I don't have an Nspire, so I can't really be super helpful here :P

]]>\begin{align} \frac{d}{dx}3tan(6x) \end{align}

Will display as the answer

(2)\begin{align} \frac{18}{(cos(6x))^2} \end{align}

Instead of simplifying the expression to

(3)\begin{equation} 18sec^2(6x) \end{equation}

Is there anyway to express trig functions in their simplest form?
