Trig identities, including even-odd, sum-difference, half-angle, double-angle, product-to-sum, and sum-to-product identities The law of sines and the law of cosines, including Heron's formula Value of sin, cos, tan repeats after 2π Shifting angle by π/2, π, 3π/2 (Co-Function Identities or Periodicity Identities) Angle sum and difference identities Double Angle Formulas Triple Angle Formulas Half Angle Identities (Power reducing formulas) Sum Identities (Sum to Product Identities) Product Identities (Product to Sum Identities Half-angles in half angle formulas are usually denoted by θ/2, x/2, A/2, etc and the half-angle is a sub-multiple angle. 2 Evaluate the Cosine of the Reference Angle We need to find cos150∘. Several trigonometric ratios and identities help in solving problems of trigonometry. cos (105°) Explanation To find the exact value of cos(83π), we recognize that 83π is exactly half of 43π. The values of trigonometric angles 0°, 30°, 45°, 60°, 90°, and 180° for sin, cos, tan, cosec, sec, and cot are determined using a Complete table of half angle identities for sin, cos, tan, csc, sec, and cot. 5∘), we observe that 22. Since 43π is a standard angle on the unit circle, we can apply the half-angle identity.
