1. Write down the linear (tangent line) approximation to y = e / at the point x = 0, and sketch the graph of this function and the tangent line.Q2. Give the first 3 non-zero terms of the Taylor polynomial approximation to sin xabout the point x = 0.Q3. Let N be the second last digit of your student number, so N = 3. Use the Taylor polynomial of Q2 to give an approximation to sin N?? Q4. Using the remainder formula for the Taylor polynomial approximation, esti-mate the error in your approximation to sin N??.
