    Exclamation effective annual interest rate

    I am stuck on this problem: I am asked to graph the effective annual interest rate u(n)% corresponding to a nominl annual rate of 10% compounded n times per year. Use the window settings 1 is less than or equal to n less than or equal to 365; 0 is less than or equal to x less than or equal to 356; 10 is less than or equal to y less than or equal to 10.6.
    I am asked to determine the effective annual interest rate corresponding to a 10% per annum nominal rate: compounded monthly and compounded daily. How would I go about setting up the window? I guess that is the first place to start.
    Thank You,

    It sounds to me that you are being asked to plot this on a specific device.
    If so it might help if you told us what that device was.

    On the system I usually use this would be done with the setplot function, in
    this case the command would look like:

    >setplot(1,365,10,10.6)

    That is "setplot(xmin,xmax,ymin,ymax)"

    But your device probably has some other way of doing this.

    I have a TI-84 plus calculator and I have never used "setplot" before.
