I am looking for references and free online books of solved problems in these topics: applications of differential equations in geometry, percentage calculus, physics and geometric analysis.
By applications in geometry I mean something like this...

Homework Statement
Draw a block diagram of 32kx8 bit RAM memory using decoders DEC 3/8 and memory components 8kx8 bit.
2. The attempt at a solution
First we find the number of memory components:
N=\frac{32kx8}{8kx8}=\frac{2^{18}}{2^{16}}=4.
The number of decoders is
32/8+1=5
There are 4...
Maybe I have misunderstood the problem. I think that for each given list (second column), the order of machines along the production line such that the manufacturing process of a car is done without interruptions, if such order exists, is a hash function. Sequence that I gave in the original...
Homework Statement
In a factory, machines are making cars (1-n) along the production line. One machine is making one part on the existing construction (part 1 is made by machine 1,...). Installation order of some parts is not important, but some parts have to be installed before others...
An article https://en.wikipedia.org/wiki/Problem_of_points
says that in a game where one player needs r points to win (the one closer to winning) and the other needs s points to win, the correct division of the stakes is in the ratio of:
\sum_{k=0}^{s-1}{r+s-1 \choose k} ...
Two players, A and B, are playing a sequence of matches of some game. In each match, one player wins (there is no draw game in any match). For winning the match, the player gets 1 point, and for losing, 0 points. The match ends when one of the players first gets 6 points, and that player wins...

Homework Statement
On which orbit of hydrogen atom an electron has the speed of 734 km/s?
Homework Equations
Bohr's second postulate: mvr=nh,m=9.109\cdot 10^{-31}kg,v=734 km/s,h=6.626\cdot 10^{-34} m^{2}kg/s
The Attempt at a Solution
By using the second Bohr's postulate, we get 6686.006\cdot...
@NascentOxygen ,
Here is the solution from by book:
The complex apparent power of \underline{I_{g2}} after the switch is closed is \underline{{S_{I_{g2}}}^{(c)}}=(240+j20)mVA.
I don't know if this solution is correct.
