WebTo simplify trigonometric expressions it is necessary to know trigonometric identities and algebraic rules. It's helpful to follow some general rules: If trigonometric functions contain different angles, we try to reduce them to functions of only one angle using, for example, cofunction and reduction identities or double-angle formulas. WebMar 26, 2016 · When a trigonometric expression is a fraction with a binomial in its denominator, always consider multiplying by the conjugate before you do anything else. Most of the time, this technique allows you to simplify. For example, follow the steps to rewrite this expression without a fraction:

WebMar 27, 2024 · When simplifying trigonometric expressions, one approach is to change everything into sine or cosine. First, we can change secant to cosine using the Reciprocal Identity. secx secx − 1 → 1 cosx 1 cosx − 1 Now, combine the denominator into one fraction by multiplying 1 by cosx cosx.
WebThis can be simplified to: ( a c )2 + ( b c )2 = 1 Now, a/c is Opposite / Hypotenuse, which is sin (θ) And b/c is Adjacent / Hypotenuse, which is cos (θ) So (a/c) 2 + (b/c) 2 = 1 can also be written: sin 2 θ + cos 2 θ = 1 Note: sin2 θ means to find the sine of θ, then square the result, and sin θ2 means to square θ, then do the sine function
