# Math Help - Equation of Tangent

1. ## 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 $x = 3$

2. assuming

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

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

3. Thanks for the reply, but can you tell me how you got to that answer?

4. 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

$y- y_1 = m(x-x_1)$
