d/dx{cos[2 sin-1(cos x)]}=
If y=(ax+b/cx+d) then 2y1y3=
d/dx{Sin-12x/1+x2+Sec-11+x2/1-x2}=
The derivative of (ax+b)cx+d w.r.to x is
If x=e2tcos 3t, then d2x/dt2 at t=π/2 is
If xy=c2 then dy/dx=
If y= log sin x then y2=
If f(x)= x(√x-√(x+1)) then
If y2=a2cos2x+b2sin2x then y+y2=
d/dx{Tan-1√(1-sin x/1+sin x)}=
