# What is the equation of the tangent line of #f(x)=(x-1)^3 # at #x=2#?

y = 3x - 5

To find the equation in the form y = mx + c , where m represents the gradient and c , the y-intercept.

Given an x-coordinate, f(2) is the value of the y-coordinate and f'(2) is the value of the tangent gradient.

The "partial" equation is therefore y = 3x + c.

y = 3x + c using (2,1): 6 + c = 1 → c = -5

and the tangent equation is thus: y = 3x - 5.

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.
