Given a function f with $f + f^{″} \geq 0$ , show that $f (x) + f (x + π) \geq 0$ for all x.
Note that for sine and cosine both inequalities become equations. It seems reasonable to look at $f + f^{″} = g$ , but the resulting expressions seem inconclusive.

Contrary to a popular belief, equation in math also contains things like inequalities and expressions that require logic and verbal explanations. This is where equation help becomes useful as you look at the answers below. See equation problems submitted by students like you and explore the answers. It will help you to understand the logic as you approach equation algebra and study expressions examples. These are not as complex as they may seem once you learn how to connect expressions and equations and understand them as a finite combination of symbols, depending on use.
