1.6.2 Differentiation

For two points (x1,y1)(x_1,y_1)(x1​,y1​) and (x2,y2)(x_2,y_2)(x2​,y2​), the straight-line gradient is [...]\text{[...]}[...].

A

It starts with the limit definition of the derivative.

B

The derivative may be written as f′(x)f'(x)f′(x) or dydx\boxed{\frac{\mathrm{d}y}{\mathrm{d}x}}dxdy​​.

C

For two points (x1,y1)(x_1,y_1)(x1​,y1​) and (x2,y2)(x_2,y_2)(x2​,y2​), the straight-line gradient is m=y2−y1x2−x1\boxed{m=\frac{y_2-y_1}{x_2-x_1}}m=x2​−x1​y2​−y1​​​.

D

If P=(x,f(x))P=(x,f(x))P=(x,f(x)) and the horizontal separation is hhh, then Q=Q=Q= (x+h,f(x+h))\boxed{(x+h,f(x+h))}(x+h,f(x+h))​.
