Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error.
The total charge entering a terminal is given by q = 2e3t cos (6\pi t), in µC. Determine the current at t= 0.25 s.
