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.
In trigonometry, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined. Geometrically, these are identities involving certain functions of one or more angles. They are distinct from triangle identities, which are ...

a 2 + b 2 = c 2. Dividing through by c2 gives. a2 c2 + b2 c2 = c2 c2. This can be simplified to: (a c)2 + (b c)2 = 1. a/c is Opposite / Hypotenuse, which is sin (θ) b/c is Adjacent / Hypotenuse, which is cos (θ) So (a/c) 2 + (b/c) 2 = 1 can also be written: sin 2 θ + cos 2 θ = 1.
