Free math problem solver answers your trigonometry homework questions with step-by-step explanations.
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.
Effortlessly find trigonometric function values (sin, cos, tan, cot) or solve for missing sides or angles in a right triangle using our remarkable tool crafted by experts.

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.
Use this sin calculator to easily calculate the sine of an angle given in degrees or radians. Calculating Sin(x) is useful in right triangles such as those formed by the heights in different geometric shapes.
