How to find the value of cot?

Could you please explain to me in simple terms how one might go about finding the value of cot, also known as the cotangent function in trigonometry? I'm not very familiar with advanced math concepts, so I'd appreciate it if you could break it down for me in a way that's easy to understand. Are there any specific formulas or steps I should follow to calculate the cotangent of an angle, or is it more of a concept that I need to grasp first? Thank you in advance for your help!
