Problem 1. The Taylor Series for the exponential function is $e^x = 1 + x + \frac{x^2}{2!} + \frac{x^3}{3!} + ... + \frac{x^n}{n!} + ...$ (a) Using a for loop, compute and display the error of the Taylor series when using 12 and 15 terms, each as compared to the exponential function when evaluated at $x = 2$. (b) Using a while loop, compute and display the number of terms necessary for this function to have an error within your allowed range of 0.001 when evaluated at $x = 3$. Display this error.

1.In an induction motor, is the rotor connected to the three-phase incoming power? 2.Is the rotor speed the same speed as the rotating magnetic field of the stator? 3.If both where traveling at the same speed, there will be no induction and the rotor will not be able to create a magnetic field. 4.If we have a motor with a rated speed of 1774, how many poles does it have? 5.If we look at the speed torque curve, at what point is the torque at its maximum? 6. Which NEMA design motor will be the best for a fan or pump application? 7. What is usually given on the motor nameplate-Synchronous speed or the rated speed? 8. What does TENV on a motor name plate stands for? 9. An electromagnet is: 10. An electromagnet can be replaced by a 11.
