Trigonometric ratios in right triangles (article) Khan Academy

WebSin and Cos are basic trigonometric functions along with tan function, in trigonometry. The sine of an angle is equal to the ratio of the opposite side to the hypotenuse whereas the cosine of an angle is equal to the ratio of … WebWell, in beginning trigonometry, it's convenient to evaluate sin/cos/tan by using soh-cah-toa, but later, as you get into the unit circle and you start taking taking stuff like sin(135) and tan(-45) you don't use the adjacent-opposite-hypotenuse much anymore. If you can think of it intuitively, though, sin(90) means that the opposite side is ... WebThe ratios of the sides of a right triangle are called trigonometric ratios.
