` dy/dx` का मान ज्ञात कीजिए । यदि ` y = (x^(4))/4 - x^(3)/3 + x^(2)/2 - x+3`

Explanation

` :' y = x^(4)/4 - x^(3)/3 + x^(2)/2 - x+3`
` :. (dy)/(dx) = 1/4 d/(dx) x^(4) 1/3d/(dx)x^(3) + 1/2 d/(dx)x^(3) - d/(dx)x+ 3 d/(dx)`
` =1/4 xx 4x^(3) - 1/3 xx 3x^(2) + 1/2 xx 2x - 1+0`
` = x^(3) - x^(2) + x - 1 `
