Write a function that takes as an input two initial guesses x₀ and x₋₁ and returns a zero of the function f(x) = xsin (1/x) by using the secant method (with tolerance 10¹⁰. Then write a script to find zeros for 10 pairs of random initial guesses between 0 and 1, (you can use the function rand (10, 2) to make a 10 x 2 matrix of initial guesses). Plot the function and the zeros you find overlayed (with marker 'ro)'
