I'm really struggling on the question below, can anyone provide any tips on where to start\how I should approach this question?

The instantaneous value of a power signal may be described by;
12∠ (3π/8) [W]

Find the magnitude of the vertical and horizontal components of this signal. Note that the symbol
∠ indicates ‘angle’.

If the W is units, then 12 ang(3pi/8)
Means magnitude 12 and argument 3pi/8
So use cos and sin to get the horiz and vertical components.

Thank you,



So for the horizontal component it would be 12cos(3pi/8)

and for the vertical component it would be 12sin(3pi/8)
