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.

Trigonometric functions and their reciprocals on the unit circle. All of the right-angled triangles are similar, i.e. the ratios between their corresponding sides are the same. For sin, cos and tan the unit-length radius forms the hypotenuse of the triangle that defines them.
Free math problem solver answers your trigonometry homework questions with step-by-step explanations.
The three main functions in trigonometry are Sine, Cosine and Tangent. They are just the length of one side divided by another. For a right triangle with an angle θ : Sine Function: sin (θ) = Opposite / Hypotenuse. Cosine Function: cos (θ) = Adjacent / Hypotenuse. Tangent Function: tan (θ) = Opposite / Adjacent.
18 lip 2024 · sin(α) = opposite/hypotenuse. cos(α) = adjacent/hypotenuse. tan(α) = opposite/adjacent. Remember that cotangent, secant, and cosecant are the inverse of the previous functions: csc(α) = 1/sin(α) = hypotenuse/opposite. sec(α) = 1/cos(α) = hypotenuse/adjacent. cot(α) = 1/tan(α) = adjacent/opposite
