student number is 61

3) (30 pts) In this problem, the last two digits of your student number will be significant. Let N, be a number equal to the last digit of your student number, N, be a number equal to the last two digits of your student number. That is, if the last three digits of your student number is 83 then, N, = 3, N = 83. Consider a function f(x) = cos (1 x defined and continuous on the interval [N1, N2]. Using the Least Squares method find a polynomial of degree two approximating this function. For the solutions, you must only use a calculator and you have to show all the details. 3) (30 pts) In this problem, the last two digits of your student number will be significant.
