## Calculus (3rd Edition)

(a) If $X$ is not a mouse, then $X$ is not a rodent. (b) If you do not sleep late, you will not miss class. (c) If a star does not revolve around the sun, then it is not a planet.
To find the inverse of $A\implies B$, we negate $A$ and $B$. Thus, the inverses are: (a) If $X$ is not a mouse, then $X$ is not a rodent. (b) If you do not sleep late, you will not miss class. (c) If a star does not revolve around the sun, then it is not a planet.
