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 }}...
aLet me also cheer for the return of SBTG. Hopefully we'll have Geometry and Physics for subjects, where we learn physics terms like "the sum of the forces is equal to zero" or "what's the cosine of a right triangle?" 也让我为SBTG回归欢呼。 有希望地我们将有几何,并且物理为主题,我们...

Similarly, the cosine is defined as it is the trigonometric function which is equal to ratio of the length of the adjacent side to the length of the hypotenuse. There are six basic trigonometric ratios for the right-angled triangle. They are sin, cos, tan, cosec, sec, cot which stand...
