      \frac{d}{dx} \sin x &= \cos x &
      \frac{d}{dx} \cos x &= -\sin x \\[2ex]
      \frac{d}{dx} \tan x &= \frac{1}{\cos^2 x} = \sec^2 x &
      \frac{d}{dx} \cot x &= -\frac{1}{\sin^2 x} = -\csc^2 x \\[2ex]
      \frac{d}{dx} \sec x &= \sec x\cdot \tan x &
      \frac{d}{dx} \csc x &= -\csc x \cdot \cot x
