3. (258) Use the Newton-Raphson method to calculate Vit. Perform as many iterations as needed so that the first four digits after the decimal point do not change any more. Start your iteration with an initial guess of 1.4. (Hint: you need to first define a function so that Vi is the root of that function.] Note: You won't receive any points if you use other methods. 3.
