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}=
If 3x2+4xy+2y2+x-8=0 and dy/dx at (1,1),(1,2),(2,-1),(-1,3) are respectively A,B,C,D then the descending order of A,B,C,D is
d/dx { log√(cosec x+1)-√(cosec x-1)}=
The derivative of (sin x)x w.r.to x is
If |x|<1 then d/dx[1+px/q+p(p+q)/2!(x/q)2+p(p+q)(p+2q)/3! (x/q)3+...]
