Question 1
Two oscillators, one with amplitude A1 and phase Ο1 and another with amplitude A2 and phase Ο2, are represented by phasors. Derive the resultant amplitude and phase of these oscillators.
π‘ Hint: Consider visualizing the phasors as vectors and using the triangle rule for addition.
Question 2
Given a phasor with an angular velocity of Ο that is offset by a phase angle of Ο/3, compute its projection on the real axis after time t.
π‘ Hint: Remember to compute the value of cosine at the specific angle to find the projection.
