Given. Two pair of values x1=5,y1=4,x2=1,y2=1/2. Calculate the Pythagorean triples associated with each pair?

choli [55]

The so-called pythagorean triple will just be the distance between both points,

$\bf ~~~~~~~~~~~~\textit{distance between 2 points}\\ \quad \\
\begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~{{ 5}} &,&{{ 4}}~) 
% (c,d)
&&(~{{ 1}} &,&{{ \frac{1}{2}}}~)
\end{array}\qquad 
% distance value
d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2}$

$\bf d=\sqrt{(1-5)^2+\left( \frac{1}{2}-4 \right)^2}\implies d=\sqrt{(-4)^2+\left( -\frac{7}{2} \right)^2}
\\\\\\
d=\sqrt{16+\frac{7^2}{2^2}}\implies d=\sqrt{16+\frac{49}{4}}\implies d=\sqrt{\frac{64+49}{4}}
\\\\\\
d=\sqrt{\frac{113}{4}}\implies d=\cfrac{\sqrt{113}}{\sqrt{4}}\implies d=\cfrac{\sqrt{113}}{2}$

Prove that if d|m and d|n, then d|(m+n)

Mila [183]

$d\mid m$ means to say there is some $k_1$ such that $m=dk_1$ . Similarly, $d\mid n$ is equivalent to saying there exists $k_2[/te]x such that [tex]n=dk_2$ .

Now, $m+n=dk_1+dk_2=d(k_1+k_2)=dk_3$ , i.e. there is some $k_3$ such that $m+n$ is a multiple of $d$ , i.e. $d\mid(m+n)$ .
