Hi all,

In a calculation (working through a Laplace Transform problem in a circuits book), I get a result "cos ((3/4)*pi - 2*x)", but I would much prefer something with a positive value for the variable and the phase constant, preferably with the phase to the right instead of the left, like "cos(2*x + BLAH)".

Is there a flag or a trig symbolic rewrite to make this happen?

I tried using "trigcos()" on it but it doesn't change it.

I am using the 2018-07-xx firmware.

(Also "trigcos(cos(-x+pi/2))", just playing around, yields "sin(x)" which seems like the wrong rewrite for the command. Just saying.)

Thanks for the help!
