In trigonometry, and geometry, the trigonometric functions give a relation where an angle is defined in terms of two sides of a right angled triangle. For example, cosine, sine, tangent, secant, etc. Answer and Explanation:1 The function given in the quest...
All trigonometricfunctionsare periodic in nature. Trigonometric ratios are used to find the missing sides or angles in a triangle. Examples on Trigonometric Ratios Example 1:In a right-angled triangle ABC, right-angled at B, hypotenuse AC = 10 units, base BC = 8 units and perpendicular AB =...
Example 1. Evaluate tan 120°.Answer. The corresponding acute angle of 120° is 60°. Therefore, according to the theorem,tan 120° = ±tan 60° = ±In the second quadrant, tan θ (y/x) is negative. Therefore,tan 120° = −....
