Question 1114028
.
<pre>
The line  y = x/2  has the slope of 0.5.


Hense, the angle w is  such that  tan(w) = 0.5,  i.e.  w = atan(0.5).


Then  tan(2w) = {{{(2*tan(w))/(1-tan^2(w))}}} = {{{(2*0.5)/(1-0.5^2)}}} = {{{1/(1-1/4)}}} = {{{1/((3/4))}}} = {{{4/3}}}.


Thus  m = tan(2w) = {{{4/3}}}.


<U>Answer</U>.  m = {{{4/3}}}.

Solved.
