Trigonometric Ratios in a TriangleDefinition : For any acute angle α , we draw a right triangle that includes α . The sine of α , abbreviated sin α , is the ratio of the length of the leg opposite this angle to the length of the hypotenuse of the triangle....
(Mathematics) the branch of mathematics concerned with the properties of trigonometric functions and their application to the determination of the angles and sides of triangles. Used in surveying, navigation, etc. Abbreviation:trig [C17: from New Latintrigōnometriafrom Greektrigōnontriangle] ...
Trigonometric ratios are the ratios of the length of sides of a triangle. These ratios in trigonometry relate the ratio of sides of a right triangle to the respective angle. The basic trigonometric ratios are sin, cos, and tan, namely sine, cosine, and tangent ratios. The other important tr...
Triangle Ratios In our study of similarity and right triangle trigonometry we will need the definition of one type of triangle. Let ABC be a triangle with a right angle. Then, it is called a right triangle. Observe Right triangle ABC with sides measuring a, b and c In the next figure,...
Trigonometry Table which gives the trigonometric ratios of standard angles 0°, 30°, 45°, 60° and 90° for Sin, Cos, Tan, Sec, Cot, Cosec functions.
Trigonometric ratios are ratios of the lengths of the three sides of a right triangle. These ratios define trig functions.
