To solve a trigonometric simplify the equation using trigonometric identities. Then, write the equation in a standard form, and isolate the variable using algebraic manipulation to solve for the variable. Use inverse trigonometric functions to find the solutions, and check for extraneous solutions.

Use the form to find the variables used to find the amplitude, period, phase shift, and vertical shift.
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. Negative angles imply the same way to calculate sine and cosine (vertical and horizontal projections, respectively), with the difference that angular rotation occurs in the clockwise direction.
Cosine period is equal to 2π; It's an even function (while sine is odd!), which means that cos(-α) = cos(α); and Cosine definition is essential to understand the law of cosines – a very useful law to solve any triangle.
