Answer:
The sine function is the opposite side divided by the hypotenuse, so the cosecant function is the hypotenuse divided by the opposite side. The side opposite the right angle is called the hypotenuse, and the other two sides are called legs.
In trigonometry, the law of cosines relates the lengths of the sides of a triangle to the cosine of one of its angle.
cos=B/H
The Law of Sines is the relationship between the sides and angles of non-right (oblique) triangles . Simply, it states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all sides and angles in a given triangle.
sin=P/H
