Trigonometric Ratios of Allied Angles Two angles are said to be allied when their sum or difference is either zero or a multiple of 90°. The angles — θ, 90° ± θ, 180° ± θ, 270° + θ, 360° —θ etc., are angles allied to the angle θ, if θ.
Grade 12 Revision – Trigonometry (Compound Angles) Prepared by: Mr. C. Hull ! “Compound” angles are simply the sum of, or the difference between, two other angles Basic Trigonometry and Radians 2007 Mathematics IA & IMA Revision/6 Problems Using Trigonometry Example: For a person viewing a tall build-ing, the angle of elevation of the top of the

The angles 30°, 45° and 60° appear frequently in trigonometry and their sine, cosine and tangent ratios can be expressed using rational numbers and surds. EXERCISE 3. PLANE AND SPHERICAL TRIGONOMETRY 3 angles and the rotation matrix of direction cosines. Finally, in section 3.8, a number of commonly encountered trigonometric formulas are gathered for reference. 3.2 Plane Triangles. This section is to serve as a brief reminder of how to solve a plane triangle. While there may be a temptation to pass rapidly over this section, it does contain a warning.
