Sin Cos Tangen. For a given angle θ each ratio stays the same no matter how big or small the triangle is. The three main functions in trigonometry are sine cosine and tangent.
Sine cosine and tangent often shortened to sin cos and tan are each a ratio of sides of a right angled triangle. The sine cosine and tangent functions express the ratios of sides of a right triangle. To which triangle s below does sohcahtoa apply.
The three main functions in trigonometry are sine cosine and tangent.
This page explains the sine cosine tangent ratio gives on an overview of their range of values and provides practice problems on identifying the sides that are opposite and adjacent to a given angle. But we must know which sides. The sine cosine and tangent functions express the ratios of sides of a right triangle. The tangent is the same as the slope of the hypotenuse.
