trigonometry


trigonometry table, tabulated values for some or all of the six trigonometric functions for various angular values. Once an essential tool for scientists, engineers, surveyors, and navigators, trigonometry tables became obsolete with the availability of computers.

How to find the values? To learn the table, we should first know how sin cos tan are related We know that tan θ = sin θ/cosθ sec θ = 1/cos θ cosec θ = 1/sin θ cot θ = 1/cot θ Now let us discuss different values For sin For memorising sin 0°, sin 30°, sin 45°, sin 60° and sin 90° We should learn it like sin 0° = 0 sin 30° = 1/2 sin 45° = 1/√2

Trigonometric formulas are formulas that used to solve problems based on the sides and angles.



A Guide to Advanced Trigonometry Before starting with Grade 12 Double and Compound Angle Identities, it is important to revise Grade 11 Trigonometry. Special attention should be given to using the general solution to solve trigonometric equations, as well as using trigonometric identities to simplify expressions.

Question 1. From the given figure, find the value of x: Answer: In the given fig., only one side is known which is hypotenuse and side to be evaluated is BC which is perpendicular with reference to given angle ZA = 30°. ∴ sin 30° = x 15 ⇒ x = 15 sin 30° x = 15 × 12 = 7 12 cm Question 2. If tan A = cot B, prove that A + B = 90°. Answer:
