Solving Equations Involving a Single Trigonometric Function. When we are given equations that involve only one of the six trigonometric functions, their solutions involve using algebraic techniques and the unit circle (see Figure 2).We need to make several considerations when the equation involves trigonometric functions other than sine and cosine.Where b 2-4ac is called the discriminant of the equation.. Based on the discriminant value, there are three possible conditions, which defines the nature of roots as follows:. two distinct real roots, if b 2 – 4ac > 0; two equal real roots, if b 2 – 4ac = 0; no real roots, if b 2 – 4ac < 0; Also, learn quadratic equations for class 10 here..
