If $f^\prime(x)=\cos(x)$, write two different possible equations for $f$. How many equations are possible? Homework Help ✎

What function has a derivative of $\cos(x)$?

If you have not done so already, consider adding a constant to your first solution. After all, the derivative of a constant is $0$.
