Use inverse trigonometric functions to find the solutions, and check for extraneous solutions. A basic trigonometric equation has the form sin (x)=a, cos (x)=a, tan (x)=a, cot (x)=a. The formula to convert radians to degrees: degrees = radians * 180 / π.

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.
18 lip 2024 · 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. Negative angles
This trigonometry calculator will help you in two popular cases when trigonometry is needed. If you want to find the values of sine, cosine, tangent, and their reciprocal functions, use the first part of the calculator.
Free trigonometric function calculator - evaluate trigonometric functions step-by-step.
Here, we show you a step-by-step solved example of trigonometric identities. This solution was automatically generated by our smart calculator: Starting from the left-hand side (LHS) of the identity. Applying the secant identity: $\displaystyle\sec\left (\theta\right)=\frac {1} {\cos\left (\theta\right)}$.
