On #1, you seem to have forgotten the Chain Rule. Try completing the square under the radical and give some thought to a trigonometric substitution.
few integration questions that are bugging me i have made attempt on all of them some of them are not even worth mentioning how i have tried it because it got me no where near the answer.
1. i am not even sure how to begin this one.
answer = 84
attempt:
or other path i have tried as well... but wasn't sure how to exactly fully proceed
so i have tried this then...
2. this one i am not sure if i copied wrong or something but when i attempt it i get the answer of 1
question:
answer = 0.73
attempt:
3. this one gives me some problems as well. question says
find the equation that passes thru (1,0) is tangent to the line and has
answer:
4. last question says
find first quadrant area of
answer:
attempt:
first rewrite the equation to be
got the limits using table of values and got result of (2,1)
and then i am not sure if i am on the right path because it does not work out to correct answer.
