1) do it the same way I did the previous question 1
2) (bottom derivative top - top derivative bottom ) / bottom squared
( x^4 * 0 - 1*4x^3 )/x*8
= - 4 /x^5
3) x^2 cos x - sin x (2x)
you finish
1)if y=x³+2x²+7x+8 then dy by dx will be-
2) if y= 1/x⁴ then, dy by dx will be:
3) if y = x² sin x, then dy/dx will be-
