 Hi everyone in this tutorial you will learn how to use cyan function in python and how to work with cyan in radians and the gris in python. First what we need to do is to import mat module. Mat module contains many mathematical functions. If we want to find a value of a cyan we're gonna call cyan function from the mat module and we're gonna put as an argument the value in radians. I'm gonna print this result and here we got the result of cyan of one radian. But what if we want to find cyan value of an angle in the gris. If we want to do that first we need to know that constant p represents 180 degrees. So if we want for example to find sinus of 90 degrees we're going to use p over 2 which is 180 over 2 degrees and that's 90 degrees. And similarly if we want to find a cyan of 30 degrees we're gonna use p over 6 because 180 degrees over 6 is 30 degrees. For example I want to find cyan of 90 degrees so I'm gonna use this constant p from the mat module and I'm gonna divide it by 2. Here we are trying to find cyan of 90 degrees angle. Let's run this code. First I need to put this line as comment. I'm gonna run this code and here we have our result cyan of 90 degrees is one. That's all in this tutorial.
