The sine of one of the angles of a right triangle (often abbreviated “sin”) is the ratio of the length of the side of the triangle opposite the angle to the length of the triangle’s hypotenuse. The cosine (often abbreviated “cos”) is the ratio of the length of the side adjacent...
Sine (sin) and cosine (cos) are fundamental trigonometric functions that play a vital role in various areas of mathematics, physics, and engineering. The sine of an angle in a right-angled triangle is defined as the ratio of the length of the side opposite the angle to the length of the...
we get, cos 2x = cos2x - sin2x. Using the Pythagorean identity sin2x + cos2x = 1, along with the above formula, we can derive two other double angle cosine formulas which are cos 2x = 2 cos2(x) − 1 and

Hence, the cosine of 270 degrees is 0. For tangent of 270 degrees: We are well aware of the identity that $\tan \theta =\dfrac{\sin \theta }{\cos \theta }$ Thus, we can write $\tan {{270}^{\circ }}=\dfrac{\sin {{270}^{\circ }}}{\cos {{270}^{\circ }}...
x sin y (you take the sine and cosine of x x and y y and there is multiplication and addition). sin x sin x is not rational (because you are just taking the sine of x x , and there is no multiplication, division, addition or subtraction). cos x cos x is ...
