An electric circuit contains a 1-H inductor, a 3-2 resistor, and a voltage source of sin t. The resulting differential equation relating the current i and the time t is di/dt + 3i = sin t. Find i after 0.5 s by Euler's method with At = 0.1 s if the initial current is zero. Solve the equation exactly and compare the values Use Euler's method to find i after 0.5 s. 'approx =A (Round the final answer to four decimal places as needed. Round all intermediate values to nine decimal places as needed.)
