I had A+B=1 -2A + 2B= -6 multiplied top by 2 then substracted with bottom, 2A + 2B = 2 -2A +2B = -6 Subtracting the top with bottom I got 4A = 8 A = 2, sub A into the first equation 2 + B = 1 2-1 = -B -1 = B OH WHOOPS I didnt make B negative when I moved it to the other side!

ok guys thanks I solved this problem pretty sure I'm correct to, i got 2ln|x+2| + lin|x-2| + C hmm the solution says - lin|x-2| on the second part , why is it - rather than +

ohh is that the integral where we do the A/x-2 + B/x+2 thing? I don't really remember doing that a lot I forgot what the values of A and B would be

Why are you guys doing the part where its du - dx in the numerator I don't get where the dx part is coming from? and what's its value?

I have trouble solving the following integral \frac{x-6}{x^2-4} If I let u= x^2 - 4, I'm left with 1/2du = x dx and I'm stuck trying to get rid of that 6 in the numerator? If someone can help me out, that would be good.

Lol Thanks, So should I first do the formulas for the x components and the y components and then combine it..and the hypotenuse would be the answer?

Homework Statement Spacecraft 1 is launched from the surface of the Earth with a velocity of 0:6c (Earth RF) at an angle of 50 above the horizontal +x axis. Spacecraft 2 is moving with a velocity of 0:7c (Earth RF) in the x direction towards Spacecraft 1. Determine the velocity and speed of...
