Mathematics Question on Differential Calculus
If y=xex+xeforx>0,the dxdy is equal to ?
A
xex[1/x+lnx]+ex
B
xexex[1/x+lnx]+exe−1
C
ex.xex−1+exe
D
xexe−x[1/x−lnx]+exe−1
E
xexex[1/x−lnx]+exe−1
F
=ex.xex−1+e.xe−1
Answer
=ex.xex−1+e.xe−1
Explanation
Solution
y=xex+xe for x>0
Now dxdy for x>0can be represented as
dxd(xex+xe)
=ex.xex−1+e.xe−1 (_Ans)
