WebTrigonometric functions sin A = opposite / hypotenuse = a / c cos A = adjacent / hypotenuse = b / c tan A = opposite / adjacent = a / b csc A = hypotenuse / opposite = c / a sec A = hypotenuse / adjacent = c / b cot A = adjacent / opposite = b / a See also Trigonometric functions Sine calculator Cosine calculator Tangent calculator WebNotice in particular that sine and tangent are odd functions, being symmetric about the origin, while cosine is an even function, being symmetric about the y-axis. The fact that you can take the argument's "minus" sign outside (for sine and tangent) or eliminate it entirely (for cosine) can be helpful when working with complicated expressions.

Web1 I'm a little confused about how you choose to use either sine or cosine or tangent over the others. Are they interchangeable given the same information you have about a right triangle? What are the circumstances … WebLearn how to find the sine, cosine, and tangent of angles in right triangles. The ratios of the sides of a right triangle are called trigonometric ratios. Three common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan). These are defined for acute … board vertical
