- $\dfrac{d}{dx}~ (\sin x) = \cos x$
- $\dfrac{d}{dx} ~(\cos x) = -\sin x $
- $\dfrac{d}{dx} ~(\tan x) = \dfrac{1}{\cos^2x} $
- $\dfrac{d}{dx} ~( \sec x) = \sec x \cdot \tan x $
- $\dfrac{d}{dx}~ (\text{cosec} ~x) = -~ \text{cosec}~ x \cdot \cot x$
- $\dfrac{d}{dx} ~(\cot x) = -\dfrac{1}{ \sin^2x }$
