I apologize if this has been discussed before, I didn't find anything.
I'll make it short:
1. I have dual citizenship (US/EU), have spent most of my life in Europe (UK) but came to the US for college. I am 22. As a whole, I relate better to europeans and the way of life there.
2. Have a...
Hi guys, i've just completed my first year at Florida Tech with a 3.78 GPA (and completed Physics 1 and 2, and Chem 1 and 2, as well as up to Calc 3 - all with A's except Chem 1 which was a B. I also took a technical writing course and got an A). I also switched from an Astrophysics major to...
Hi all,
I just found out that the college I will be attending this Fall is no longer offering the program that I wanted to do (Computer Information Systems) as undergrad. It got me thinking about what I really want to do.
So I moved to America from the UK almost a year ago. Instead of...
Hi I have a proof i'm doing
\int \frac{1}{1+\sin(x)}dx
I know that the answer i'm looking for is
\frac{\sin(x) - 1}{\cos(x)}
and then
\tan(x) - \sec(x)
I have tried integration by parts making
u = (1+\sin(x))^{-1} and dv = dx
Eventually I get an answer that...
Hi, I recently switched from a Computer Science undergrad major at Florida Tech to Computer Information Systems. Basically because I like working with hardware, the internet, servers and networks a lot more than programming.
CIS offers half Comp Sci courses (programming in C++ and Java but...
I can't seem to figure out this problem.
Find the dimensions of the rectangle with maximum area that can be inscribed in a circle of radius 10.
I start by drawing the diagram and it seems to me like the circle radius corresponds with a line from the center of the rectangle to one of the...
I have a test tomorrow and this is a subject we only briefly touched on. I can find points of discontinuity graphically very easily, but I have no idea how to find them algebraically using just the equation.
I know that when the denominator = 0 and in most piecewise functions there is...
Doing fine until I reached a trig function where I know i've done the work correctly but the answer does not match up exactly with the one in the back of the book.
\sin(x^2y^2)=x
I do the work using product and chain rule
\cos(x^2y^2)(2xy^2+2x^2yy')=1
2xy^2+2x^2yy' = \frac {1}...
This is a problem that has stumped my entire class of Calc 1 students and two Calc 2 students.
Find \frac {dy} {dx}
y = \frac {(2x+3)^3} {(4x^2-1)^8}
I know that the answer is (from the textbook, but I don't know how it got there)
-\frac {2(2x+3)^2(52x^2+96x+3)} {(4x^2-1)^9}...
Well i've managed to handle these pretty well considering I was absolutely stumped during Limits of trig functions. However on a more difficult homework question I came out with an incredibly huge answer which was far from the real one.
Let me try latex for the first time...
\frac {dy}...
