Cotangent Function
The cotangent function, abbreviated as “cot,” is one of the six fundamental trigonometric functions. It represents the reciprocal of the tangent function and can be defined as the ratio of the cosine to the sine of an angle, or equivalently, the ratio of the adjacent side to the opposite side in a right triangle.
Mathematically, cotangent is expressed as: cot(θ) = 1/tan(θ) = cos(θ)/sin(θ). This function is particularly useful in various mathematical applications, including calculus, physics, and engineering problems involving periodic phenomena and wave analysis.
The cotangent function has a period of π radians (180 degrees) and is undefined at multiples of π where the sine function equals zero. Understanding these properties is crucial for solving trigonometric equations and analyzing periodic behavior in mathematical models.
How to Use the Cotangent Calculator
Step 1: Select Your Angle Unit
Choose the appropriate unit for your angle measurement from the dropdown menu. The calculator supports three common angle units: degrees (most commonly used in basic trigonometry), radians (preferred in advanced mathematics and calculus), and gradians (used in some engineering applications). This flexibility ensures accurate calculations regardless of your input format.
