Plus two times the second derivative of y with respect to x is equal to 1 4th. And so let's see, I have 1 8th plus two times the second derivative is equal to 1 4th. And let's see, I could subtract 1 8th from both sides. So subtract 1 8th, subtract 1 8th. These cancel, I get two times the second derivative of y with respect to x is equal to 1 4th is the same thing as 2 8ths. So 2 8ths minus 1 8th is 1 8th. And then I can divide both sides by two, and we get a little bit of a drum roll here.
