Question

transform y_1=-4sin(t/2)+3cos(t/2) into
y_2=Asin(Bt+C) using y=Msin(Bt)+Ncos(Bt)=
sqrt{N^2+M^2}sin(Bt+C)
we want to choose C such that |C| is a minimum. so i have so far y_2=5sin(t/2+C). i think C=-.644.
is that right?

Answer 1

i posted all my work
i would just like someone to check pretty please
