USING MATLAB Please post code 1. Solve the 2nd order differential equation ?+89 +15y-sin(t), y(0)-1,?(0)-2 symbolically and numerically, and plot both results together over the time interval 0,10 sec. Provide appropriate labels on both axes, a title, and a legend that denotes each solution. Check your symbolic answer by using the Matlab DIFF function to compute the appropriate derivatives and then substituting them into the differential equation.

Solve the problem. In economics, functions that involve revenue, cost and profit are used. Suppose R(x) and C(x) denote the total revenue and the total cost, respectively, of producing a new high-tech widget. The difference P(x) = R(x) - C(x) represents the total profit for producing x widgets. Given R(x) = 60x -0.4 x2 and C(x) = 3x + 13, find the equation for P(x). P(x) - 60x -0.4x2 P(x) = -0.4x2 +57x - 13 P(x) = -0.4x2 +63x +...
