Problem (int means the integral sign):

d/dx( int(arccos(t^7)dt) from 2 to x )

the answer is arccos(x^7) but can you explain the steps? Is the fundamental theorem of calculus involved? This was very poorly explained in my book and I wanted to see if any of you have insight...

How would you do a probelm like the following?

it has (y^5)^3(y^3)^2
-----------------
(y^4)^4

It look s even more confusing written out like that
so in breif it has (yto the 5) to the 3(y to the 3)to the 2
on top of a division line and under the line is
(y to the 4) to the 4
everything that is in parenthasies is also in the parenthasies on the problem.

Two point charges are located on the x axis: one charge, q1 = -11.0 nC, is located at -1.715m ; the second charge, q2 = 34.5 nC , is at the origin (x=0). What is the net force exerted by these two charges on a third charge q3= 52.0 nC placed between q1 and q2 at x3 = -1.145 ? Use 8.85×10−12 for the permittivity of free space.

What could this mean? My friend had a brain MRI done ("...with and without contrast"). And that was the result. What do you know about those findings. What does that mean. The doctor was dismissive about it, my friend said, telling him "..you should not worry about it", and then changed the conversation.

My friend says there is some history of Alzheimer's in his family, but he's not sure if it is an isolated case only.

Is there a definite link between those finding and Alzheimer's? Could that "atrophy" get reversed either w intervention of some sort or by itself?

I would really appreciate a any input from someone educated/professional in a related field of study. Anyone?
