7.4 Sum and Difference Identities
In this chapter, you will be learning about the Sum and Difference Identities (which will be super useful). Videos with Explainations and Examples
7.3 Trigonometric Equations
In this section, we will develop methods for solving trigonometric equations from simple types of equations to types that must be factored or solved by quadratic equation. Conditional solution General form solution More Review Videos
7.2 Verifying Trigonometric Identities
In this chapter, we will be focusing on proving trigonometric identities (very fun!!!). The eight fundamental identities will be very important in this section (so make sure you memorize the basic identities). Expression: no equal signs. Equations: statement that is true for a set of specific values. Identity: an equation that is true for all…
7.1 Trigonometric Identities and Equations
Welcome back to our Math Department Blog! In this chapter, you will be learning about trigonometric equations and identities. Although there are infinitely many trigonometric identities, there are a few basic ones that you will need to have memorized. Verifying Identities The six trigonometric ratios that you already know from the previous chapter: The Reciprocal…
