[" 11."(ax)/(b)-(by)/(a)=a+b],[" ax "-by=2ab" ."quad [CBSE2007C]]

Solve the following equations: (ax)/(b)-(by)/(a)=a+b , ax-by=2ab.

Solve the following system of equations by method of cross-multiplication: (ax)/(b)-(by)/(a)=a+b,quad ax-by=2ab

intsin(ax+b) dx = -(cos(ax+b))/a + c, a ne 0

intsec^2(ax+b)=(tan(ax+b))/a +c,a ne0

int (ax+b)/(ax^2+2bx+c) dx

int (2ax+b)/(sqrt(ax^2+bx+c))dx

Show that it the curves ax^(2) +by^(2)=1 " and " Ax^(2) +By^(2) =1 are orthogonal then ab(A-B)=AB(a-b).

Show that the lines ax+by+c=0, ax-by+c=0, ax-by=c ax+ by-c=0 (a ne b) enclose a rhombus whose area is (2c^(2))/(ab) sq unit.
