the question states: Is the integral, from 0 to 5, ln(x)/(x+2) dx, an improper integral? do not try to compute this integral. the answer: Yes, ln(x) undifined when x = 0. WHAT, why is this so, i thought an improper integral is when i take the upper/lower bound and replace it with...

i know the following: q = x+y+z ERROR IN q = sqrt((error in x^2)+(error in y^2)+(error in z^2)) but, what if the equation i have is q = x+y-z would it still be that same equation or would it be, ERROR IN q = sqrt((error in x^2)+(error in y^2)-(error in z^2))

using Darcys law... ...what is Cross sectional area of cylinder?

alright but won't i need to have these two formulas into one, and put this over the m_1 formula?

for m_2 friction and tension are on x N normal is on y and m_2*g is between neg y and x axis

ok this just really confused me, N is equal to normal force right? and this just boggled me even more im not solveing for any numbers I am trying to find the equation using the variables which is even more confusing.

so wait would (m_1)ax= (m_1)*g and (m_1)ay=o ? or am i just really confused, if so then how do i intergrate m_2ay & m_2ax into an m_2a equation?

still don't get it drawn the free body diagrams and not understanding how to construct the formula, can anyone help?

so frikin confused tried too many times, can anyone help me out? *image attached* Block 1, of mass m_1, is connected over an ideal (massless and frictionless) pulley to block 2, of mass m_2, as shown. Assume that the blocks accelerate as shown with an acceleration of magnitude a and that...

Consider a high pressure gas cylinder of methane which exhibits a pressure of 200 atmosphers (absolute) at a temp. of 0*C in a small storage building. the building catches fire whcih causes the temp of the cylinder to rise to 1200*C. What would the pressure in the cylinder be then? express your...

1) the given function is defined for x>0 except for x=2. Find the value to be assigned to f(2), if any, to guarantee that f is continuous at 2. f( x ) = sin(pi x) / (x-2) cant figure out how to change the equation so i can plug 2 in, i think I am loking right past it, tried multiplying...

still not sure how you got rid of the 1/2...and did the m just cancel out on each side?

ok..haveing trouble understanding some examples in the book... 1) 1000kg rocket is fired striat up, need rocket to escape and never return. what speen does rocket need to escape from grav pull to never come back?(non rotating earth) i know rocket can't stop so or it will be drawn back into...

see, that just blew over my head, I am still boggled

it says nothing about friciton
