How to Calculate Cotangent
by aafr in Education
Cotangent is one of the basic functions of trigonometry. (Some of the others are sine, cosine, secant, cosecant and tangent.) The cotangent is defined as the ratio of the length of the adjacent leg of the triangle to the length of the opposite leg.Difficulty:ModerateInstructions Things You'll Need

How to Find the Cotangent on a Graphing Calculator
by UglyCasanova in Education
In trigonometry, the cotangent is the reciprocal of the tangent. The formula for determining the tangent is the opposite side divided by the adjacent side of a triangle. So, since the cotangent is the reciprocal, then the formula for determining the cotangent is the adjacent side divided by the opposite side of the triangle. When inputting cotangent into a graphing calculator, you need to know the

How to Graph Cosecant, Secant & Cotangent
by skulldrinker in Education
The two basic trigonometry functions are the sine and cosine functions. The sine function is the "y" coordinate of an angle on a unit circle, and the cosine function is its "x" coordinate. The other four trigonometry functions can be derived from these two functions. Cosecant is the multiplicative inverse of the sine function, secant is the multiplicative inverse of the cosine function, tangent is

How to Graph Tangent & Cotangent Functions
by Barry in Education
The tangent is a trigonometric function defined as the sine divided by the cosine. Another way of defining it is the tangent of an angle is the ratio of the side opposite the angle divided by the side adjacent to the angle in a right triangle. For example, in a triangle with sides of 3, 4 and 5 inches, the angles will be 90 degrees, 53 degrees and 37 degrees .The side opposite the 37-degree angle

How to Calculate Cosecant, Secant & Cotangent
by boomhower in Education
The cosecant, secant and cotangent are all reciprocal trigonometric functions. They are calculated in similar ways to the conventional functions sine, cosine and tangent to solve for unknown angles. Although a basic problem, solving for values in right triangles represents the core of trigonometry with applications in many different science and engineering fields. Before you can use any trigonome

How to Find Sine, Cosine, Tangent and Cotangent
by sarah in Education
Sine, tangent, cotangent and cosine are all functions when dealing with right triangles. Sine, tangent and cosine are the primary functions of trigonometry. When you see these functions in trigonometry problems, these functions are written as sin, tan and cos. Although graphing calculators can figure sine, tangent,cotangent and cosine for you, figuring them yourself is not difficult once you un
