f(x,y)=square root x^2+y^2
The function you provided is a mathematical function of two variables, x and y. It calculates the square root of the sum of the squares of x and y.
To understand how this function works, let's break it down step by step:
1. Start with the two variables, x and y.
2. Square the value of x (x^2).
3. Square the value of y (y^2).
4. Add the squared values of x and y together (x^2 + y^2).
5. Take the square root of the sum (sqrt(x^2 + y^2)).
So, for any given values of x and y, you can use this function to calculate the square root of the sum of their squares.
For example, if x = 3 and y = 4:
1. Square the value of x: (3^2) = 9.
2. Square the value of y: (4^2) = 16.
3. Add the squared values together: 9 + 16 = 25.
4. Take the square root: sqrt(25) = 5.
So, f(3, 4) = 5.
