Cotangent is a trigonometric function. It is the reciprocal of the tangent.
LOTS- cubic - quadratics - reciprocal - hyperbola - trigonometric - and more
The sine of an angle is the cosine of its complement and conversely. The tan of an angle is the reciprocal of its complement.
Yes, but it is called a hyberbolic trigonometric function
A reciprocal refers to a mathematical expression or function, that when multiplied by a number, the product is always 1. The reciprocal of 23 is 1/23.
In Mathematics, "reciprocal" defines a quantity or function related to another so that their product is one. 2/3 is the reciprocal of 3/2 and vice versa.
TRIGONOMETRIC FUNCTIONS OF ANY ANGLE
It is a trigonometric function. It is also continuous.
The product of a number and its reciprocal is always one. That's what reciprocal means.
I find it convenient to express other trigonometric functions in terms of sine and cosine - that tends to simplify things. The secant function is even because it is the reciprocal of the cosine function, which is even. The tangent function is the sine divided by the cosine - an odd function divided by an even function. Therefore it is odd. The cosecant is the reciprocal of an odd function, so it is naturally also an odd function.
The product of -1 and -1 is 1. The reciprocal of a fraction is called its reciprocal.
