differentiation

d(x⁴/4 + x³/3 - x)dx > d(x⁴/4)dx

=> x² - 1 > 0

Now solve.

I assume you mean rate of change of expression is greater than rate of change of x⁴/4

is this not like this??????

d(x⁴/4 + x³/3 - x)dx>x⁴4

i thought thiscoz ques is not like this:::

For what values of x, the rate of change of x⁴/4 + x³/3 - x is more than tht of x⁴ /4??

True..I misread the question.

@ pasushah bhaiiya i hope u can proceed with the inequality x³+x²-x>x⁴4
