735° = 15° ---> tan 735° =tan 15° Hence, tan 735° is equal to tan 15°. Problem 2 : Evaluate : cos (-870°) Solution : Since the given angle (-870°) has negative sign, we have to assume it falls in the fourth quadrant. In the fourth quadrant, "cos" is positive. S...
tan 0 1/√3 1 √3 Undefined Sine (sin) function gives the ratio of the length of the opposite side to the length of the hypotenuse in a right triangle. Cosine (cos) function gives the ratio of the length of the adjacent side to the length of the hypotenuse. Tangent (tan) function ...

The double angle formula is used to calculate sin 2y, cos 2y, tan 2y, for any given angle 'y'. The tangent double angle formula states that for an angle 'y', tan 2y = 2 tan y/{1-tan^(2) y}. What is sin 2x double angle? The double angle formula is used to calculate sin...
Sin, Cos and Tan Sin, Cos and Tan A-Level Maths, Quadrants and the "cast" Rule On a set of axes, angles are measured anti-clockwise from the positive x-axis. So 30° would be drawn as follows: Image The angles which lie between 0° and 90° are said to lie in the first ...
