Since the cotangent function is NOT defined for integer multiples of π, there are vertical asymptotes at all multiples of π in the graph of cotangent. Also, from the unit circle (in one of the previous sections), we can see that cotangent is 0 at all odd multiples of π/2. Also, from the unit circle, we can see that in an interval say (0, π), the values of cot decrease as the angles increase. Thus, the graph of the cotangent function looks like this.
- It is, in fact, one of the reciprocal trigonometric ratios csc, sec, and cot.
- As we look at the behavior of cot(x) over the interval of 0 to 2π, we’ll see that it actually completes a full cycle and returns to its initial value just after π.
- If in a triangle, we know the adjacent and opposite sides of an angle, then by finding the inverse cotangent function, i.e., cot-1(adjacent/opposite), we can find the angle.
- It is usually denoted as “cot x”, where x is the angle between the base and hypotenuse of a right-angled triangle.
- Alternative names of cotangent are cotan and cotangent x.
How do You Find the Angle Using cot x Formula?
- Let us learn more about cotangent by learning its definition, cot x formula, its domain, range, graph, derivative, and integral.
- The period of a trigonometric function is the interval in which the function repeats its values.
- The symmetry of trigonometric functions determines whether they are even or odd, which simplifies calculations in integrals and derivatives and helps analyze their graphs.
- Also, we will see the process of graphing it in its domain.
We can also find the above properties from the graphs of the respective trigonometric functions. If in a triangle, we know the adjacent and opposite sides of an angle, then by finding the inverse cotangent function, i.e., cot-1(adjacent/opposite), we can find the angle. In this section, let us see how we can find the domain and range of the cotangent function. Also, we will see the process of graphing it in its domain. Each trigonometric function has distinct restrictions on its inputs (domain) and outputs (range), primarily due to its periodic and geometric nature.
Domain, Range, and Graph of Cotangent
The period of a trigonometric function is the interval in which the function repeats its values. So basically, if we know the value of the function from \(0\) to \(2\pi\) for the first 3 functions, we can find the value of the function at any value. More clearly, we can think of the functions as the values of a unit circle. Trigonometric functions are the simplest examples of periodic functions, as they repeat themselves due to their interpretation on the unit circle.

Understanding these properties helps solve equations and simplify expressions.
Examples on Cotangent
It is usually denoted as “cot x”, where x is the angle between the base and hypotenuse of a right-angled triangle. Alternative names of cotangent are cotan and cotangent x. Let us learn more about cotangent by learning its definition, cot x formula, its domain, range, graph, derivative, and integral.
Just like other trigonometric ratios, the cotangent formula is also defined as the ratio of the sides of a right-angled triangle. The cot x formula is equal to the ratio of the base and perpendicular of a right-angled triangle. Here are 6 basic trigonometric functions and their abbreviations. Since both sine and cosine functions have a period of 2π, when we observe cotangent, it effectively cancels out some of this periodicity. As we look at the behavior of cot(x) over the interval of 0 to 2π, we’ll see that it actually completes a full cycle and returns to its initial value just after π. It is, in fact, one of the reciprocal trigonometric ratios csc, sec, and cot.

Also, we will analyze forex market see what are the values of cotangent on a unit circle. The periodicity identities of trigonometric functions tell us that shifting the graph of a trigonometric function by a certain amount results in the same function. The symmetry of trigonometric functions determines whether they are even or odd, which simplifies calculations in integrals and derivatives and helps analyze their graphs. In the same way, we can calculate the cotangent of all angles of the unit circle.
