Use the definition of the derivative at a point to find an eq for the tangent line to y= x^3 at the point (1,1) . No points for any other methods help??

Answer 1

Tangent at #(1,1)# is #y=3x-2#

Let us consider tangent to a curve #y=y(x)#, as shown below (in red line) at point #A#. To find the equation of tis tangent, we need the coordinates of the point #A#, as well as slope of tangent. This allows us to use point-slope form of the equation.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
