Square of trig functions

[Will Foreman]

Hello all,

tl;dr

Is there a way to represent sin^2, sec^2, etc. in JME?

I am making a question that includes differentiating a trig function which I have randomised. In the answer, I have {derivative}({a2}x). The variable a2 is just an integer and derivative is an expression. This works fine when derivative is cos or -sin (eg. it could expect cos(3x)), but when it is sec^2 it thinks sec is a variable so expects sec^2*3x. This also happens for sin^2 and cos^2 Is there a way to get around this, or a better way to input sec ^2?

Many thanks,

Will

This problem is so old that Charles Babbage wrote a whole essay about how much he didn't like sin^2: https://books.google.co.uk/books?id=kQ8bAQAAMAAJ&newbks=1&newbks_redir=0&printsec=frontcover&pg=PA527&dq=%22although+a+definition+cannot+be+false+it+may+be+improper%22&hl=en&redir_esc=y#v=onepage&q=%22although%20a%20definition%20cannot%20be%20false%20it%20may%20be%20improper%22&f=false

Put the power after the brackets, e.g. sin(x)^2.
