hey minor problem, i have two phasors i need to add:
44.7cos(ωt-161°) + 126.5(ωt + 63°)
how do i add them when one is a cos and the other is a sin, the answer is supposed to be given as a sin, but i cant find anything similar in my notes.
the answer is 100sin(ωt +45°).
all i need to know is how to write the equation with cos in it as a sine.
thanks for any help, i have an exam on monday so help is much appreciated.
