Evaluate ∫-x/(x+1) dx
Homework Equations
The Attempt at a Solution
I do a U-sub
u=x+1
du=dx
x=u-1
-∫(u-1)/u du
-∫[u/u - 1/u] du
-∫1 - 1/u du
-[∫1du - ∫1\u du]
-[u - ln(u) + C]
ln(u)-u+C
ln(x+1)-(x+1)+C
ln(x+1)-x-1+C
I combine -1 and C into a single C to get...
This is the frirst SR problem in his book. I think the question is flawed.
The solution assumes a speed of 3.00 E8 m/s to calculate Δt=333us since it traveled 100km.
Next, 333us and 2.2us is used to solve for velocity using the time dilation formula. Velocity is reported to be .999978c...
Can anyone explain this to me?
If we have an infinite amount of balls arranged in a kind of cubic matrix, in an infinite and static space...how the heck would that collapse on itself due to gravity?
Thanks folks
I have been searching for the requirements for entry into physics graduate programs.
I am seeing GRE + physics GRE + 3 LORs
Is it understood that the student has a strong background in physics or mathematics or do they really not require it?
I have signed up for higher mathematics...
Question:
Which best describes the delta G for hydrolysis of creatine phosphate under cellular conditions in which the concentration of creatine phosphate, creatine, and phosphate all equal 1 mM at 25 degrees C. The delta G naught for the hydrolysis of creatine phosphate at 25 degrees C is...
1) if you have 2 line segments making a right angle, and connect the endpoints with a line segment with an outward curve relative to the vertex, will the area inside always be irrational?
2) if you have 2 line segments making a right angle, and connect the endpoints with a line segment with an...
I'm free-falling towards a planet.
Inertial or not?
I suppose this is a postulate of general relativity isn't it?
When I'm studying special relativity I would say Non-inertial, but then if I think about how I cannot really tell if I am accelerating or just traveling a constant...
