Find v (t). i (t) 10 uH 1000 pF Hint: from trigonometry, cos(a + b) = cos(a) cos(b)-sin(a) sin(b) cos(a-b) = cos(a) cos(b) + sin(a) sin(b) Adding these two equations removes the sin terms, giving cos(a + b) + cos(a-b) = 2 cos(a) cos(b) Therefore, a signal that is the product of two cosine waveforms at given frequen- cies can...
