True or false :

If we differentiate the function sinh ⁡ x \sinh x with respect to x x twice, we obtain the very same function.

Similarly, if we differentiate the function sin ⁡ x \sin x with respect to x x twice, we obtain the very same function.

d d x sin ⁡ ( x ) = cos ⁡ ( x ) \dfrac{d}{dx}\sin(x)=\cos(x)

d d x cos ⁡ ( x ) = − sin ⁡ ( x ) \dfrac{d}{dx}\cos(x)=-\sin(x)

Hence the answer is false.
