    Equation of Tangent

    Hey, just started this year's calc class and I have a question:

    If \dfrac{f(x)g(x)} {h(x)}

    Write the equation of the tangent to y and x = 3

    assuming

    If y(x) = \dfrac{f(x)g(x)}{h(x)}

    then the tangent will be y- y(3) = y'(3)(x-3)

    The equation of a tangent to a function y at x = 3 can be given by

    y- y(3) = y'(3)(x-3)

    which is a straight line and comes from the form

    y- y_1 = m(x-x_1)
