WebOct 24, 2024 · CBSE Class 10 Maths Notes Chapter 8 Introduction to Trigonometry. Position of a point P in the Cartesian plane with respect to co-ordinate axes is represented by the ordered pair (x, y). Trigonometry is the science of relationships between the sides and angles of a right-angled triangle. Trigonometric Ratios: Ratios of sides of right triangle ... WebMay 31, 2011 · cos (60°) = b/6. 6×cos (60°) = b = 3. To solve for a value, two parts of the trigonometry equation must be present out of the 3 (angle equals sidelength over sidelength). In this case we used Sine and Cosine because they each used the hypotenuse and the reference angle opposite of the right angle (2 out of 3 parts).
