You might not know what you have until its gone.

Thanks a lot! I got the answer and have a better understanding of circuits! By the way thanks for not giving me the answer, haha. For those others trying the question the answer is: i2=0.833A

Homework Statement Calculate i2, given that r1=12, r2=6, r3=12, r4=6. There is a 20V source. The first step here is calculate Req, I believe. http://media.newschoolers.com/uploads/cache/images/1222468444-632813-600x325-1222468266Untitled2423423.jpg Homework Equations Req=(r1 ll r2)...

Homework Statement Assume the function f(x)=x^3+x has an inverse in R. Determine d/dx(f^-1(x)) at x=2. Homework Equations (f^-1(x))'=1/f'(f^-1(x)) The Attempt at a Solution y'=3x^2+1 (f^-1(x))'=1/(3y^2+1) now i substitute f^-1(2), y=10, into the equation but do not get...

Hello, I will be attending university next year to study engineering and I need a laptop that will help me in my studies. I just have a few questions about what type to get because I have no idea and I thought the professional engineers or students still studying engineering could help provide...

Homework Statement This question is concerning a limit question. I have no problems finding limits but i need to be able to factor this equation. I need to be able to some how get rid of the (x-1) (x^(1/6)-1)/(x-1) The Attempt at a Solution I ust keep ending up in a loop geting a...

ok i got the answer but i do not think that i did it the right way. please take a look at my steps Definition: Average Speed = [Distance Traveled]/[Time Taken to Travel that Distance] 1. I pretend the distance traveled one way up the hill is 10m, therefore 20m round trip. 2. I then...

so while going down the hill would the distance then become 2D?

A car traveled up a hill at constant speed of 10.0 m/s and then returned down the hill at 20.0 m/s . If the time to turn around is ignored, what was the average speed for the trip? Now i like to struggle to figure out questions myself but i can't seem to figure this one out. I have most of...

now I am only a high school student but it sounds like the competition to get into biomedical engineering is very feirce is this true?? Like do people usually complete a bachelors before getting accepted?

im also very interested in this career path. Is there a lot of math and physics involved as well as the chem and biology part? If u can post some good information on this career please post a link. thanks.

yes i do it means 1/a i just can't get the answer. i have to go to school now so ill post my work when i get home

please help me with this quest i cannot figure it out (please show your work thanks!) sry i made a mistake this is not algebra. it is sloving complex fractions Determine a polynomial or rational algebraic expression in simple form equivalent to each of the following: C3 1+(a+a^-1)^-1...

is it not possible to download these videos (shapiro) onto my hard drive? I am going on a trip and would like to be able to watch them on my psp or video ipod. If you know how please message me or reply below. So far i have watched them and i have to say i can't get enough of them! They...
