Question 9) Find the Maclaurin Series for each of the following functions. Give the radius of convergence. You may use any of the established series (a) f(x) = 10+ z (b) g(x) = (10)² (Hint: Use part (a)) (c) h(x) = cos(3x) (d) j(x) = 2x³ ln(1 + 2x)

Solve for x: z=x.

The formula for the amount A in an investmentaccount with a nominal interest rate r at any timet is given by A(t)=a(e)rt, where a is the amount ofprincipal initially deposited into an account thatcompounds continuously. Prove that the percentageof interest earned to principal at any time t can becalculated with the formula I(t)=ert1.
