    Pythagorean array theorem Pythagorean array theorem: each primitive Pythagorean array (a, B, c) (where a is odd and B is even) can be obtained from the following formula: a = st\\ b = \frac{s^2-t^2}{2}\\ c = \frac{s^2 + t^2}{2} amongs>t\geq 1Is any odd number that has no common factor.The proof process is as follows:Considering the […]

    We describeda^2 + b^2 = c^2All integer solutions ofa,b,c, ifc^2Divide by this equation (\frac{a}{c})^2 + (\frac{b}{c})^2 = 1 So rational numbers are right(\frac{a}{c},\frac{b}{c})It’s an equationx^2 + y^2 = 1The solution ofequationx^2 + y^2 = 1Represents a circle C with a center at (0, 0) radius of 1. How to find the points on circle C […]

    Pythagoras theorem (Pythagorean theorem) indicates that the sum of the squares of the lengths of the two right angles of any right triangle is equal to the square of the length of the hypotenuse. It is expressed by formula a^2 + b^2 = c^2 The first question is whether there are infinitely many Pythagorean arrays […]
