sec2 x −tan2 x sec 2 x − tan 2 x. = (1 +tan2 x) −tan2 x = ( 1 + tan 2 x) − tan 2 x. = 1 = 1. But in your question you mentioned reciprocals, so I am assuming you can't use the above identity. In that case, you can do the following: Writing sec2 x as 1 cos2 x sec 2 x as 1 cos 2 x and tan2 x tan 2 x as sin2 x cos2 x sin 2 x cos 2 x : sec2
Below are some of the most important definitions, identities and formulas in trigonometry. Trigonometric Functions of Acute Angles sin X = opp / hyp = a / c , csc X = hyp / opp = c / a tan X = opp / adj = a / b , cot X = adj / opp = b / a cos X = adj / hyp = b / c , sec X = hyp / adj = c / b , Trigonometric Functions of Arbitrary AnglesUsing the #color(blue)"trigonometric identity"#. #color(red)(bar(ul(|color(white)(a/a)color(black)(sin^2x+cos^2x=1)color(white)(a/a)|)))# divide all terms on both This section is an introduction to trigonometric identities. As we discussed in Section 2.6, a mathematical equation like is a relation between two expressions that may be true for some values of the variable. To solve an equation means to find all of the values for the variables that make the two expressions equal to each other. An identity gfIVb. 2 316 144 358 187 429 24 94 464
