Answer» Here the fomula is say that d/dx logx=1/x then according to your question \'e\' is ignore here becausethe rules of calculas say that in one formula we can use only one variable like-( x/y/a........) ,eg-d/dt Sint= cost ,when you can use two or more variablethen it is wrong ,eg-(d/dx Tn=nx n-1)this is wrong
