Thread Subject: how to do this : sin(x)*cos(y)+sin(y)*cos(x)= sin(x+y)

i'm using Maple Toolbox For Matlab,
using command :
> syms x y
>simple(sin(x)*cos(y)+sin(y)*cos(x))
but do not show the result : sin(x+y)
how to do this ?

Hi,
It is pretty simple. The solution to your problem is
maple('combine','sin(x)*cos(y)+sin(y)*cos(x)','trig')
The matlab symbolic toolbox will access the maple kernel to simplify the equation.
