Question 1:

Approximate cos(0.18) to five decimal-place accuracy using the MacLaurin series for cos(2). cos (0.18) ~dy a. Set up an integral for solving when y(0) = 0. de 72 - 1 y(@) = + b. Evaluate your answer to the previous part to find y(2). y(@) = help (formulas)Consider the initial value problem y' = 5y , y(0) = yo. For what value(s) of yo will the solution have a vertical asymptote att = 8 and a t-interval of existence -co
