Find a formula for fn and prove it by mathematical induction. Recall that o represents function composition. i.e., (f o g)(x) = f(g(x)).Answered by Stephen La Rocque.     The interior angles of a right triangle 2006-05-20 From Greg:I am wondering if there is a way to figure out the interior angles of a right triangle if we know ONLY the side lengths, and the trick is, we CANNOT use arctangent!Answered by Leeanne Boehm and Penny Nom.     Solving x - sin(x) = constant 2000-12-29 From Keith Roble:If x is in radians, how do you solve for x, where: x-sin(x) = constant?Answered by Harley Weston.
