Can anybody help with this math question? It involves differentiation.
A control system has a time constant, τ ( = 1/t)), where t satisfies the equation 10e-2t = 2Sin2t + 3. Show that this equation has a solution between t = 0 and t = 1. Use the Newton-Raphson method to calculate this value of t correct to three decimal places. Hence calculate the time constant τ for this circuit.
