Below is the graph of a cosine function in the form y = acos(bx)

Use the function nest to evaluate p(x) = 1 + x + · · · + x50 at x = 1.00001. (use the matlab ones command to save typing.) find the error of the computation by comparing with the equivalent expression q(x) = (x51 − 1)/(x − 1).

What is the equation of a vertical line passing through the point (−5, −1)? y = −5 y = −1 x = −5 x = −1
