Best ResponseYou've already chosen the best response.0I have a sample problem. I've tried applying the steps to the actual problem but it's confusing.

Best ResponseYou've already chosen the best response.0So instead of substituting 6 and 1 into the v's, you'll substitute 5 and 2.

Best ResponseYou've already chosen the best response.0The substitution takes place at the part where the expression is in square brackets. [ ]

Best ResponseYou've already chosen the best response.0You'll plug in 5 first and evaluate. Keep that answer on the side somewhere. Then you'll go back to the square brackets again, plug in 2 and evaluate. Whatever you get as the answer, you'll subtract that from the answer you got when you plugged in 5.

Best ResponseYou've already chosen the best response.0Okay, so if I plug in 1, I'll get 3/2+8 = 6.5

Best ResponseYou've already chosen the best response.0Then I get: (7.5+4.5)  (3/2 +8) = 9.5 or 19/2.

Best ResponseYou've already chosen the best response.0You're doing more than what it's asking for. The only values you're evaluating are 5 and 2. Not 6 and 1.

Best ResponseYou've already chosen the best response.06 and 1 are solely used in the example.

Best ResponseYou've already chosen the best response.0You never answered my question. What do you get when you evaluate the expression I wrote above?

Best ResponseYou've already chosen the best response.0Awesome. Now imagine the 5 is gone and a 2 is in its place in the expression above. What do you get now?

Best ResponseYou've already chosen the best response.0Replace BOTH 5s with 2s. Not just the one on the left.

Best ResponseYou've already chosen the best response.0Perfect. Now the last step is subtracting that 6 from 7.5: 7.5  6 =

Best ResponseYou've already chosen the best response.0But if you look at the sample problem, they subtracted another part too.

anonymous

Best ResponseYou've already chosen the best response.0They subtracted the value of the expression when a 1 was plugged in. We subtracted the value of the expression when a 2 was plugged in.

Best ResponseYou've already chosen the best response.0It's okay. Can you help with another problem?

Best ResponseYou've already chosen the best response.0Start off exactly as the example starts by dividing u and 4 by the square root of u. This gives you: \[\int\limits_{1}^{9}u ^{1/2}4u ^{1/2}\]
