Trigonometry. Trigonometry is a branch of mathematics concerned with relationships between angles and side lengths of triangles. In particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths.
Free math problem solver answers your trigonometry homework questions with step-by-step explanations.
As a consequence, we can relate the functions at different angles with the following trig identities for any n integer: sin(θ + 2πn) = sin(θ); cos(θ + 2πn) = cos(θ); and. For example a trig function at 90° (π/2) will be mathematically the same as at 450° (5π/2), as 5π/2 = π/2 + 2π.
