y=(4x^(3)-5x^(2)+1)^(4), Find (dy)/(dx)
Text Solution
|
y=(5x^3-4x^2-8x)^9,f i n d(dy)/(dx)
Text Solution
|
यदि y = ( 5x^(2) + 6x+7)/(2x^(2) + 3x + 4) तो dy/dx का मान ज्ञात क...
Text Solution
|
y=tan^(-1)((5x+1)/(3-x-6x^(2))) find dy/dx
Text Solution
|
y=tan^(-1)((5-x)/(6x^(2)-5x-3)) find dy/dx
Text Solution
|
यदि y=sin^(-1) ((6x)/(1+9x^(2))) हो तो (dy)/(dx) ज्ञात कीजिये
