What NOT to do in Calculus.

DON’T draw a sheep made of hearts with your new pink pen.

DON’T become fascinated with how your new pink pen writes, and…

DON’T doodle half a page of tiny pink hearts.

Because, trust me, little pink hearts ain’t gonna graph the rational function for you.

And yet, the above still exist…

*** Sigh.

I should start taking my own advice.
