### Find phasor representation for the sinusoidal variables

(See attached file for full problem description) Problem 4. Find phasor representation for the following sinusoidal variables. Obtain the expression for the phasors in a+jb form. a. v1(t) = 10 cos wt + pi/4) b. i2(t) = 5 sin (wt - pi/4) c. i4(t) = 10 cos (wt +pi/4) +5cos(wt - pi/4) d. v3(t) = 10 cos (wt) + 10 sin (wt)
