Question

i dont understand cosine, sin,and tangent Help?!!

Answer 1

i know what is cosine, sin,and tangent

Answer 2

Then how do you apply it to Pyh therom or triangle excuse my english.

Answer 3

Oooh trigonometry(: okay, so:
\[\sin=\frac{opposite}{hypoteneus}\]
\[\cos=\frac{adjacent}{hypoteneus}\]
\[\tan=\frac{opposite}{adjacent}\]

Answer 4

In mathematics, the sine function is a trigonometric function of an angle. The sine of an angle is defined in the context of a right triangle: it is the ratio of the length of the side opposite that angle to the length of the hypotenuse.

Answer 5

Sine, cosine and tangent
The sine of an angle is the ratio of the length of the opposite side to the length of the hypotenuse. (The word comes from the Latin sinus for gulf or bay,[1] since, given a unit circle, it is the side of the triangle on which the angle opens.) In our case

Note that this ratio does not depend on size of the particular right triangle chosen, as long as it contains the angle A, since all such triangles are similar.
The cosine of an angle is the ratio of the length of the adjacent side to the length of the hypotenuse: so called because it is the sine of the complementary or co-angle.[2] In our case

The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side: so called because it can be represented as a line segment tangent to the circle, that is the line that touches the circle, from Latin linea tangens or touching line (cf. tangere, to touch).[3] In our case

The acronyms "SOHCAHTOA" ("Soak-a-toe", "Sock-a-toa", "So-kah-toa) and "OHSAHCOAT" are commonly used mnemonics for these ratios.

Answer 6

Thanks @goformit100 I was also going to mention SOH CAH TOA but I didn't know how to explain it(:

Answer 7

lol great then....@Kitt020912 HAPPY PROMISE DAY
