This function is positive when an angle is in the first or second quadrants, and it squared equals one minus cosine of x squared.
An extended law named for this function has a 2R term, and this function is used in the Fourier transforms of odd functions. The hyperbolic type of this function is equal to e to the x minus e to the negative x all over two. The magnitude of the (*) cross product of two vectors equals the product of their magnitudes times this function of the angle between them, and the derivative of this function is cosine of x. This function is positive when an angle is in the first or second quadrants, and it squared equals one minus cosine of x squared. For ten points, name this function of an angle which is equal to the side opposite that angle over the hypotenuse in a right triangle.
