The image shows a handwritten mathematical derivation in blue ink on a white sheet of paper. The calculations involve trigonometric functions and identities, including sine, cosine, and their relationships. Some steps are marked with equal signs, fractions, and symbols indicating simplification or transformation. There are additional markings around the equations, and a diagram that could be a stick figure drawn at the bottom of the page.
