### Differentiating Other Functions (Trig, ln & e etc)

#### How do I differentiate common functions?

• These are the common results

#### How do I differentiate exponentials and logarithms?

• The two basic differentiation formulae are:

• From those basic formulae are derived these two additional formulae:

• And for exponentials more generally:

• This last formula can be derived from Formula 3 by using the chain rule
