A. f(x) is continuous but not differentiable at x=0
B. f(x) is differentiable at x=0
C. f(x) is not differentiable
D. none
If y2=a2cos2x+b2sin2x then y+y2=
d/dx{Tan-1√(1-sin x/1+sin x)}=
If f(x)=√(x+2√(2x-4))+ )=√(x-2√(2x-4)) then
d/dx{x1/x}=
d/dx {Tan-14x/1+5x2+Tan-12+3x/3-2x}=
If x2+y2=a2 then dy/dx=
If y=(x+√x2-1)m then (x2-1)y2+xy1=
The derivative of cosec-1(ax)w.r.to x is
