You pass a sign on the highway that looks like this:

What it really said

But what I saw was this:

What I saw

I’m not kidding… I’ve started solving math problems in my head while sitting in traffic on my way home from school.

It’s not right.

F(x) = \dfrac{2x}{18}*\dfrac{2x}{20} can be simplified to F(x) = \dfrac{x^2}{90}

F'(x) = \frac{x}{45}

F'(4) = \frac{4}{45}

F'(11) = \frac{11}{45}

See??? I’m sick!  I need help!

In better news, I want to thank Calculus for helping me get a 99 on my first Chemistry test… it was so much math and I couldn’t have done it without you, Calculus class.
