What amplitude must be used when combining pcosx+qsinxp\cos x+q\sin xpcosx+qsinx?
A
R=p2+q2R=\sqrt{p^2+q^2}R=p2+q2, with R>0R>0R>0.
B
Rcos(x+α)R\cos(x+\alpha)Rcos(x+α).
C
c+Rc+Rc+R, where R=p2+q2R=\sqrt{p^2+q^2}R=p2+q2.
D
13sin(x+tan−1(512))13\sin\left(x+\tan^{-1}\left(\frac{5}{12}\right)\right)13sin(x+tan−1(125)).
