D. 1/2√1-x2
If f(x)=√(1-√(1-x2)), then
If x2+y2=a2 then (1+y12)3/2/|y2|=
The derivative of (x2+1)5(2x+3)3 w.r.t is
If x= a(2 cos θ+cos 2θ), y= a(2 sin θ+sin 2θ)then dy/dx=
If y= x log|x+√(1+x2)|-√(1+x2) then dy/dx=
d/dx{√(1+cos x)/sin x}=
If y={sin x/2 sin x2/2. Sin x3/23...sin xn/2n}then dy/dx=
If y=acos2x+b sin2x, then y2+4y=
d/dx{cos[2 sin-1(cos x)]}=
If y=(ax+b/cx+d) then 2y1y3=
