Find the intervals in which f (x) = |x−2|/ (x2) is strictly increasing and strictly decreasing.
Ans: f(x)= |x-2|/ x 2 case 1: x-2 < 0 or x<2 ............................................. (1) then f(X) = - (x-2)/ x 2 = -1/x + 2/x 2 for strictly increasing d f(x)/ dx >0 d f(x)/...

Find the equation of the lines which pass through the point of intersection of the lines 4x-3y-1=0 and 2x-5y+3=0 and are equally inclined to the axes.
Intersection point of 4x-3y-1=0 & 2x-5y+3=0 is (1,1). if lines are equally inclined with the axes then slope of lines either 1 or -1. so equations of lines are y-1=1(x-1) & y-1=-1(x-1)...
