[" Example 12.Show that the removal of the term in "xy" is possible from every equation of "],[" the form "ax^(2)+2hxy+by^(2)=1]

Form the differential equation from ax^(2) + by^(2) = 1

Find the angle through which the axes be rotated to remove the xy term from the equations ax^(2) + 2hxy + ay^(2) = 0

Why we need rotation for Removal of term xy from F(x,y)=ax^(2)+2hxy+by^(2)

If the product of the perpendiculars drawn from the point (1,1) on the lines ax^(2)+2hxy+by^(2)=0 is 1, then

If the product of the perpendiculars drawn from the point (1,1) on the lines ax^(2)+2hxy+by^(2)=0 is 1, then

If ax^2+2hxy+by^2=1 Find dy/dx

Form the differential equation from Ax^(2)+By^(2)=1

Find the angle through which the axes be rotated to remove the xy term from the equation ax^(2)+2hxy+ay^(2) = 0

Show that the angle of rotation of the axes to eliminate xy term in the equation ax^(2) + 2hxy + by^(2) = 0 " is " (1)/(2) Tan^(-1) ((2h)/(a - b)) " when " a ne b and pi //4 when a = b
