1. P9 - Differentiation

2.  Constant:
 A value which always remains the same e.g. -5, -
0.25, 0, 1.5, 7
 Variables:
 A value which may change in a problem or
equation.
 Functions:
 y = f(x) = sin x
 y = f(x) = 2x3 + 3

3. y = f(x) – the function
y =K , any constant
y =x
y =axn
y =sin x
y =eax
y = f(x) – the function
y =3
y =2x = 2x1
y =3x2
y =sin x
y =e3x
