Calculate Miter Angle for 38-Degree Crown

What happens here

Using a scientific calculator (demonstrated on a smartphone), the presenter inputs the formula for determining the miter angle: `atan(cos(complementary angle) ÷ tan(half angle))`. For a 38-degree spring angle crown molding, the complementary angle is 52 degrees. For a standard 90-degree corner, the half angle is 45 degrees. Plugging these values into the formula: `atan(cos(52) ÷ tan(45))` yields approximately 31.6 degrees. This is the miter setting that should be set on the miter saw.

Goal: Determine the correct miter saw setting for a 38-degree spring angle crown molding
