Please i need help in solving this using matlab program Prob

Problem 2 (a) Find the first 3 positive ( > 0) roots of the equation: sin(x) = x * cos(x). Roots must be given with at least 8 decimal digits accuracy. (b) Find a solution of the system of equations , near x = 1 and y = 1. Problem 3 Plot the function y = x cos(x) and z = 1/5 x^2 sin(x) for x from 0 to 5 in the same figure. Use different line types. Label the axes properly. Use legend to differentiate between the curves. Add grid

Solution

a)
