Who needs solar?

True, ” I said. ” asked Angus. ” “Z = Z 0 e r t is a function that satisfies the differential equation. ” asked Marsha. “If you replace Z in the differential equation with Z 0 e r t , the equation will hold. Look, let’s take the derivative of Z = Z 0 e r t . ” 25 CHAPTER 2 “This should be fun,” said Gunderson. “I remember the derivative of e x is e x ,” said Angus. “It’s the only function that is its own derivative. You used to say it’s the only function that gives birth to itself, making it its own mother.

A critical point is an x-value where the derivative equals 0,” said Angus. “Then the tangent line’s horizontal. ” “That’s right, Angus,” I said. Gunderson ignored me. “Clearly,” he continued, “as x gets large, either positive large or negative large, the function 1 1 x2 f (x) = √ e − 2 = √ shrinks to 0. So it peaks x2 2π 2π e 2 at x = 0, when f (x) = √12π , and it shrinks to 0, for any large positive or negative x. ” “But why is the √12π in the front? That just makes it look ugly,” said Angus.
