I am asked to find the square roots using the bisection method for x * x - a = 0. I was wondering how the bisection method is performed. Let's suppose a = 9, so I would need to find the roots of x * x - 9 = 0. Also, from the 1st equation, when would the bisection method NOT output a root?

(a) Let n = 2k be an even integer. Show that x = rk is an element of order 2 which commutes with every element of Dn. (b) Let n = 2k be an even integer. Show that x = rk is the unique non-identity element which commutes with every element of Dn. (c) If n is an odd integer, show that the identity is the only element of Dn which commutes with every element of Dn.

1). Consider the quadratic equation x^2+ 100 x + 1 = 0 (i) Compute approximate roots by solving x^2 -100 x = 0 (ii) Use the quadratic formula to compute the roots of equation (iii) Repeat the computation of the roots but use 3 digit precision. (iv) Compute the relative absolute errors in the two 3 digit precision root approximations in (iii). (v) With x1 =1/2a (-b + sqrt b^2 - 4ac and x2 = 1/2a (-b + sqrt b^2...

Implement in MATLAB the Newton-Raphson method to find the roots of the following functions. (a) f(x) = x 3 + 3x 2 – 5x + 2 (b) f(x) = x2 – exp(0.5x) Define these functions and their derivatives using the @ symbol. For example, the function of part (a) should be f=@(x)x^3 + 3*x.^2 - 5*x + 2, and its derivative should be f_prime=@(x)3*x.^2 + 6*x - 5. For each function, use three initial values for x (choose between -10...
