Sine, Cosine and Tangent (often shortened to sin, cos and tan) are each a ratio of sides of a right angled triangle: For a given angle θ each ratio stays the same no matter how big or small the …

In trigonometry, sin, cos, and tan are the basic trigonometric ratios used to study the relationship between the angles and sides of a triangle (especially of a right-angled triangle). Understand …

In basic trigonometry computes sine, cosine, tangent, and their reciprocal. Calculates arcsin, arccos, and arctan values inside inverse trigonometric equations. Trigonometric identities …

Conventionally, an abbreviation of each trigonometric function's name is used as its symbol in formulas. Today, the most common versions of these abbreviations are "sin" for sine, "cos" for …

Sine, Cosine and Tangent are all based on a Right-Angled Triangle. They are very similar functions ... so we will look at the Sine Function and then Inverse Sine to learn what it is all …

$$\cdot$$ Tan Practice 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 …

Cosine is just like Sine, but it starts at 1 and heads down until π radians (180°) and then heads up again. In fact Sine and Cosine are like good friends: they follow each other, exactly π /2 …
