1. Problem 1: Find two non-zero roots of the equation
sin(z) - 2²+1/2 = 0
Explain how many decimal places you believe you have correct, and
how many steps of the bisection method it took. Try to get as many
correct digits as you can. Also include timing results for your calcula-
tions.
2. Problem 2: Same as problem 1, but for the equation
are-d
= 0
