Tangent - Math.net
WEBBelow is a graph of y=tan(x) showing 3 periods of tangent. In this graph, we can see that y=tan(x) exhibits symmetry about the origin. Reflecting the graph across the origin produces the same graph. This confirms that tangent is an odd function, since -tan(x)=tan(-x). General tangent equation. The general form of the tangent function is
Sine, Cosine, Tangent - Math is Fun
WEBSine, 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 triangle is. To calculate them: Divide the length of one side by another side
Trigonometric functions - Wikipedia
WEBSin(θ), Tan(θ), and 1 are the heights to the line starting from the x-axis, while Cos(θ), 1, and Cot(θ) are lengths along the x-axis starting from the origin. If the acute angle θ is given, then any right triangles that have an angle of θ are similar to each other. This means that the ratio of any two side lengths depends only on θ.
Intro to the trigonometric ratios (video) | Khan Academy
WEBSin, cos, and tan are trigonometric ratios that relate the angles and sides of right triangles. Sin is the ratio of the opposite side to the hypotenuse, cos is the ratio of the adjacent side to the hypotenuse, and tan is the ratio of the opposite side to the adjacent side. They are often written as sin (x), cos (x), and tan (x), where x is an ...
Tangent Calculator - calculates tan(x) for degrees or radians
WEBTangent function ( tan (x) ) The tangent is a trigonometric function, defined as the ratio of the length of the side opposite to the angle to the length of the adjacent side, in a right-angled triangle. It is called "tangent" since it can be represented as a line segment tangent to a circle. In the graph above, tan (α) = a/b and tan (β) = b/a.

WEBMay 5, 2024 · The law of tangents describes the relationship between the tangent of two angles of a triangle and the lengths of the opposite sides. Specifically, it states that: (a - b) / (a + b) = tan(0.5(α - β)) / tan(0.5(α + β)) Although the law of tangents is not as popular as the law of sines or the law of cosines, it may be useful when we have ...
