An electric circuit, consisting of a capacitor, resistor, and an electromotive force can be modeled by the differential equation dq 1 R- +で c9 = E(t), dt where R and C are constants (resistance and capacitance) and q(t) is the amount of charge on the capacitor at time t. For simplicity in the following analysis, let R = C = 1, forming the differential equation dq/dt +q = E (t). In Exer- cises 17–20, an electromotive force is given in piecewise form, a favorite among engineers. Assume that the initial charge on the capacitor is zero [q(0) = 0]. (i) Use a numerical solver to draw a graph of the charge on the capacitor during the time interval [0, 4]. (ii) Find an explicit solution and use the formula to determine the charge on the capacitor at the end of the four-second time period. 9 = 2t, if 0 < t < 2, |0, if t > 2 19. Е(()

Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
