Скачать или смотреть Learning to solve an equation by using the sum and difference formulas

👉 Learn how to solve equations using the angles sum and difference identities. Using the angles sum and difference identities, we are able to expand the trigonometric expressions, thereby obtaining the values of the non-variable terms. The variable terms are easily simplified by combining like terms and solving for x. To solve for x we will need to isolate the trigonometric functions and apply inverse trigonometric functions and the unit circle to solve. The appropriate range is applied to get the required value of x.
