What does Sine cosine and tangent mean?
Trigonometry deals with the sides and angles in triangles and the relationship between them. When the ratio involves the sides: oppositehypotenuse it is called Sine . When the ratio involves the sides: adjacenthypotenuse it is called Cosine. When the ratio involves the sides: oppositeadjacent it is called Tangent.
What is sin cos and tan in trigonometry?
Sin is equal to the side opposite the angle that you are conducting the functions on over the hypotenuse which is the longest side in the triangle. Cos is adjacent over hypotenuse. And tan is opposite over adjacent, which means tan is sin/cos.
What exactly is Sin Cos Tan?
The cosine (often abbreviated “cos”) is the ratio of the length of the side adjacent to the angle to the length of the hypotenuse. SOH → sin = “opposite” / “hypotenuse” CAH → cos = “adjacent” / “hypotenuse” TOA → tan = “opposite” / “adjacent”

Why is sin pi 6?
In this case, π6 refers to the angle in radians, an alternate unit of measurement for angles ( π rad = 180°). The point on the unit circle that is intersected by this line is ( √32 , 12 ). Finally, the function, sin( θ ) returns a value equal to the y-coordinate of the point, giving us an answer of 12 .
What is sin PI 4 pi 4?
The exact value of sin(π4) sin ( π 4 ) is √22 . The exact value of cos(π4) cos ( π 4 ) is √22 .
