If a,b,c,d are constants such that what is the value of the sum a+b+c+d? Thanks!

Use L'Hopital's rule. you get (0+b+c+d)/0 I think the only way this limit can exist is if b+c+d = 0 we then get the indeterminate form 0/0 Use L'Hopital's rule again. we get 2a/4 as the limit so a/2 = 3 and a = 6.

Unless I made a mistake somewhere, 6 is the final answer.
