Derivatives of Trig Functions: In general, sinx)=cosx ' In general, cosx )=−sinx ' 2 1 In general, tanx )=sec x= 2 (you can derive this cos x using the trig and quotient rules) In general, secx )=tanx∗secx (you can derive this using tri and quotient rules) The Chain Rule: If f is differentiable at g(x)'and g is differentiable at x, then [f ∘g )x ]= f g( (x))g '(x) ' ' ' ' [(f ∘g∘h )(x)]=f g(h( x ))( h (x))h (x) Example: x f (x)=2 f(x = ln2
