Product rule with chain rule (derivation wrt time)

  1. Dec 14, 2009 #1
    I'm trying to find the derivative of 0 = 3xcosƟ with respect to time.

    I know I should use the product rule for x and cosƟ. But I don't know what I should do with the constant 3.

    would it be like this?

    0 = 3x(-sinƟ)(dƟ/dt) + 3(dx/dt)(cosƟ)

    Yes, that's correct.
