The minimum value of x3-9x2+24x-12 is
The maximum value of x2-x+1/ x2+x+1 is
If y=x3-ax2+12x+5 is increasing for all real values of x, then a lies between
Two tangents are drawn from the point (-2, -1) to the parabola y2 = 4x. If α is the angle between those tangents then tan α =

The equation of the normal to the curve y2=x3/2a-x at (a, a) is
The point on the curve x2=2y which is closest to the point (0, 5) is
The approximate change in y, when y=x2+2x, x=3, δx=0.01 is
If the tangent to the curve xy+ax+by=0 at (1, 1) is inclined at an angle tan-2 with x-axis, then
The angle between the curves x2+y2=4 and x2=3y is
