yeah i see it now! thanks =)

Because this was part of the notes. In the notes, we integrated with respect to x and the professor showed us how to integrate with respect to y as well. Except I didn't have time to copy that part of the notes (integration with respect to y), so I was just trying to do it just now, but I don't...

This isn't a homework question, but from my notes that I couldn't figure out (wasn't able to copy the rest of the down) I have two functions: y=x y=x^3 , 0 \leq x \leq 2 and I have to find the area between these two curves. I know how to do it with respect to x, but I have troubles...

ah i still dun understand... can we work on an example from the textbook? The example is: Find the derivative of \intcost dt from 0 to \sqrt{x} by a. evaluating the integral and differentiating the result b. by differentiating the integral directly for part a. The integral of...

For the first fundamental theorem of calculus, I don't quite understand it... I think I got the integral part, but not the interval [a,x]... can you guys help me? thx

Homework Statement y=(2x+1)/\sqrt{x^2+1} Find where are the asymptotes, where is it increasing increasing/decreasing, ect... Homework Equations The Attempt at a Solution when I took the first derivative (im trying to find where it increases/decrease), I got dy/dx =...

I don't know if I do.. is it because the absolute value of any function is always positive?

nvm. i got 19/3...

ok so from -2 to 1, it is negative and from 1 to 2 it is positive... do i just split up the integral from here? like from -2 to 1, its negative, so the integral would be negative, and from 1 to 2, it is postive so the integral would be postive... and just from inspection, would the...

Homework Statement \int|x^{2}+x-2|dx from -2 to 2 Homework Equations The integral of f(x) from a to b = F(b) - F(a) |x| = { x if x >= 0; -x if x < 0 --- Ok, I don't know how to do the definite integrals of absolute values.. was never shown an example of it in class, but I kind of...

Yea I've tried solving for the variables p and t, and it doesn't work out. When I try solving it by augmented coefficient matrix and reducing it to row echelon form, I get a row of zeros and then a number ( [ 0 0 | # ] ) Then i tried solving it using the TI-83+, and I get an "Invalid Dim" error

The second part of the question is: Fine the co-ordinate vector [v] of v relative to the basis B and I don't have a clue how to do this. Do i need to kno what's the linear transformation?

Homework Statement We know that B = { (1, -1, 2, 5) , (2,-3,-1,6) } is a basis of H. Express v as a linear combination of b(one) and b(two) Where v = (0,2,-6,8) b(one) = (1,-1,2,5) b(two) = (2,-3,-1,6) Homework Equations The Attempt at a Solution is it just v =...

ahh okay thanks. i never did it this way before :shy:

Homework Statement A car with mass of 950 kg and speed of 16 m/s approches an intersection in the positive x direction. A 1300-kg minivan traveling at 21m/s is heading towards the same intersection in the positive y direction. The car and minivan collide and stick together. Fine the speed and...
