In mathematics, an identity is an equation that is always true. When you learned how to factorexpressions and equations, you worked with several algebraic identities, including (a + b)? =a? + 2ab + b? and (a – b)³ = (a – b)(a² + ab + b²). These identities helped you to rewriteand simplify more complex expressions or equations. This, in turn, allowed you to more easilysolve problems.In this module you were introduced to trigonometric identities, including reciprocal identities,quotient identities, Pythagorean identities, and others. Like algebraic identities, you can usetrigonometric identities to help you rewrite and simplify more complex expressions or equationsin order to more easily solve problems. You can also use these identities to verify whethertrigonometric equations represent identities. There are several ways to show an equation may bean identity, but to prove it is an identity, you must verify it.Use what you know about trigonometric identities to explore the questions below.sin? e1+cos evalues for 0, substitute them into this equation, and simplify. What do your results indicate about1. Amna needs to decide if the equation-1- cos 0 is an identity. Choose 3 possiblethe equation sin = 1- cos 8? Show all your work.1+cose
