Calculus 1: Newton Raphson Method

Use Newton's method for approximating roots of functions to approximate ##\sqrt{0.99}##
Use the Newton Raphson method to approximate the real zero close to ##x = 1## until two successive approximations differ by less than 0.005 for the following function
##f(x) = 2x^2 - 3##
Starting with an initial value ##x_1 = 1##, perform 2 iterations of Newton's Method on ##f(x) = x^3 - x - 1## to approximate the root.
Use Newton's Method to approximate the solution to the following equation
##\cos{(x)} = \frac{x}{5}##
Use Newton's Method to approximate a solution to ##2\cos{(x)} = 3x## (Let ##x_0 = \frac{\pi}{6}## and find ##x_2##)
