WebMar 26, 2016 · In trigonometry, a trig function replaces the x or variable part of the quadratic formula. For example, find the solution of sin 2 x – 4sin x – 1 = 0 for all angles between 0 and 360 degrees. Instead of just x ’s, the variable terms are sin x ’s. Identify the values of the a, b, and c in the formula. The values are a = 1, b = –4, and ... WebMar 10, 2024 · To solve a right triangle using trigonometry: Identify an acute angle in the triangle α. For this angle: sin (α) = opposite/hypotenuse; and. cos (α) = adjacent/hypotenuse. By taking the inverse trigonometric functions, we can find the value of the angle α. You can repeat the procedure for the other angle.
