PG-2.16: Error Trig function missing input if in the form cos^5(x)

See https://webwork.maa.org/moodle/mod/forum/discuss.php?d=5641.

After a little investigation I see that this is not the trig function exponent form as originally reported. It is the space between the exponent and the function input that is the issue.

Is the issue with the space new in 2.16?

[drgrice1]

I think so.

I've make a hot fix branch that resolves the issue.
