    What would a gradient function of sinx look like?

    Hello, I have an assignment due in a few weeks time and I've been asked to sketch the function of sinx using radians. I've done this, but I was just wondering if I had done it right. Could someone please graph the gradient function so that I can use it as a checking device?
    Thankyou.

    f(x) = sin(x)

    The gradient function of that should be
    f'(x) = cos(x).
    So, graph cos(x).

    Thankyou for the help.
    The last question asks: What is another function that you know that appears the same as your gradient function? -- Would I just answer the function of cosx?
