Trigonometric Equations Formula With Worksheets Similarly, general solution for cos x = 0 will be x = (2n 1)π 2, n∈i, as cos x has a value equal to 0 at π 2, 3π 2, 5π 2, 7π 2, 11π 2 etc. below here is the table defining the general solutions of the given trigonometric functions involved in equations. The solutions of a trigonometric equation for which 0 ≤ x < 2π are called principal solutions. how to find the general solution of trigonometric equations? we can find the general solution of trigonometric equations using the following three results: for any real numbers x and y, sin x = sin y, implies x = nπ ( 1) n y, where n ∈ z.

How To Calculate Trig Functions Let’s look at these examples to help us understand the principal solutions: example 1. find the principal solutions of the equation sinx = 3√ 2. solution: we know that, sin π 3 = 3√ 2. also, sin 2π 3 = sin(π– π 3) now, we know that sin(π– x) = sinx. hence, sin 2π 3 = sin π 3 = 3√ 2. therefore, the principal solutions of sinx. Equations involving trigonometric functions of a variable are known as trigonometric equations. example: cos 2 x 5 cos x – 7 = 0 , sin 5x 3 sin 2 x = 6 , etc. the solutions of these equations for a trigonometric function in variable x, where x lies in between 0 ≤ x ≤ 2π, is called the principal solution. Trigonometric equations are, as the name implies, equations that involve trigonometric functions. similar in many ways to solving polynomial equations or rational equations, only specific values of the variable will be solutions, if there are solutions at all. often we will solve a trigonometric equation over a specified interval.

Example 6.1. solve the equation 2 sin θ 1 = 0 2 sin θ 1 = 0. isolating sin θ sin θ gives sin θ = − 12 sin θ = − 1 2. using the sin−1 sin − 1 calculator button in degree mode gives us θ = −30∘ θ = − 30 ∘, which is in qiv. recall that the reflection of this angle around the y y axis into qiii also has the same sine. Trigonometry general solutions of a trig equation . from the following diagram we see that sin(π θ) = sin θ and cos ( θ) = cos θ. we use this to find the solutions of some trig equations. solve sin(x) = y for x. case 1: 1≤y≤ 1, that is, the value of y is between 1 and 1, so there is a solution. the set of all solutions to sin(x) = y is.
