1.7.13 Tangents and normals

Card 1 of 24

For y=f(x)y=f(x)y=f(x), the derivative is written as [...]\text{[...]}[...].

A

The yyy-coordinate, f(a)f(a)f(a).

B

Substitute the point's coordinates into the equation.

C

The tangent to y=f(x)y=f(x)y=f(x) at x=ax=ax=a has equation y−f(a)=f′(a)(x−a)\boxed{y-f(a)=f'(a)(x-a)}y−f(a)=f′(a)(x−a)​.

D

For y=f(x)y=f(x)y=f(x), the derivative is written as dydx=f′(x)\boxed{\frac{dy}{dx}=f'(x)}dxdy​=f′(x)​.
