If f(x)=x2sin(1/x) for x≠0, f(0)=0 then
The derivative of Sin-12x/1+x2 w.r.to Tan-12x/1-x2is
If y= x2+1/(x2+1/x2+....∞), then dy/dx=
If x= et(cos t +sin t), y= et(cos t-sin t) then dy/dx=
If x-y=Sin-1 x-Sin-1 y then dy/dx=
If |x|<1then dy/dx(1-2x+3x2+...)=
d/dx{(√(a2+x2)+ √(a2-x2))/ (√(a2+x2)- √(a2-x2))}
d/dx{Tan-1√(1-x/1+x)}=
If x2-xy+y2=1 and y’’(1)=
d/dx{Tan-1(x-√x/1+x3/2}=
