Practice these questions given here to get a deep knowledge of Trigonometry. The standard angles of trigonometrical ratios are 0°, 30°, 45°, 60° and 90°. Trigonometry is distinguished from elementary geometry in part by its extensive use of certain functions of angles, known as the trigonometric functions. The sine, cosine and tangent of the standard angles are given below in the table. 5. The values of trigonometrical ratios of standard angles are very important to solve the trigonometrical problems. In order to read or download trigonometric functions problems and solutions ebook, you need to create a FREE account. x = 10 / tan(51°) = 8.1 (2 significant digits) H = 10 / sin(51°) = 13 (2 significant digits) Area = (1/2)(2x)(x) = 400 Solve for x: x = 20 , 2x = 40 Pythagora's theorem: Throughout history, trigonometry has been applied in areas such as geodesy, surveying, celestial mechanics, and navigation. In this process, our eye move through an angle. (Remember a right triangle contains a 90° angle) A right triangle can be formed from an initial side x and a terminal side r, where r –  Trigonometry is one of the branches of mathematics which deals with the relationship between the sides of a triangle (right triangle) with its angles. Some of the special trigonometric identities are as given below –. sinA=Perpendicular/Hypotenuse=5/13 If the object is above the horizontal from the eye, we have to lift up our head to view the object. pdf. SOLUTION 6 : Differentiate .
