Explanation:
The distance between the two points is calculated according to the Pythagorean theorem for the triangle of which the cathets (x2-x1) and (y2-y1)
The distance between the two points is calculated according to the Pythagorean theorem for the triangle of which the cathets (x2-x1) and (y2-y1)
d2 = (x2-x1)2 + (y2-y1)2
d = sqrt (pow (x2-x1) + pow (x2-x1)), where functions from math are used
d = sqrt (pow (x2-x1) + pow (x2-x1)), where functions from math are used
For quadrature: pow (a, b) where a is the basis of the degree and b is the exponent of the degree
For rooting: sqrt (a) where a is a sized size
For rooting: sqrt (a) where a is a sized size
