These are some equations that I recently developed and submitting for review.

Evaluations?, comments?

Iterated trigonometric differentiation:

[tex]\frac{d^n}{dx^n} \sin x = \sin \left(x + \frac{n \pi}{2} \right)[/tex]

[tex]\frac{d^n}{dx^n} \cos x = \cos \left(x + \frac{n \pi}{2} \right)[/tex]

Iterated trigonometric integration:

[tex](I^n \sin)(x) = \sin \left( x - \frac{n \pi}{2} \right)[/tex]

[tex](I^n \cos)(x) = \cos \left( x - \frac{n \pi}{2} \right)[/tex]
