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 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.
