On this blog I am going to explain the relationships between the following functions:
Sine and Cosine
Tangent and Cotangent
Sine and Cosecant,
Cosine and Secant
Sine, Cosine & Tangent.
In a right triangle, there are three sides and two non-right angles. All triangle have a adjacent side, opposite side, and hypotenuse.
Opposite is opposite to the angle θ.
Adjacent is adjacent (next to) to the angle θ.
Hypotenuse is the long one.
Sine is the length of the side opposite to an angle and the length of the triangle's hypotenuse and cine is the length of the side adjacent to an angle and the length of the triangle's hypotenuse.
Tangent and cotangent are both the length of the side opposite to an angle and the side adjacent to the angle.
Cosine and secant are the length adjacent side to an angle and the length of the triangle's hypotenuse.
Sine, cosine,and tangent are related because when put them together they form a right triangle.
You need to go over something we learned and work an example problem. We did not talk about triangles this week.
