How do I convert K1*cos(w*t+theta1) + K2*sin(w*t+theta2) to a single K3*sin(w*t+theta3). Maple keeps simplifying to the cos + sin form but that is not user friendly for the signal viewed on the oscilloscope. The conversion is easy to do with a calculator but I want to automate the process in Maple with parameters so I do not have to copy and paste expressions or type them.

 

Thanks for your help,
