 >:D     exp(-((x-4)^2+(y-4)^2)^2/1000) + exp(-((x+4)^2+(y+4)^2)^2/1000) + 0.1exp(-((x+4)^2+(y+4)^2)^2)+0.1exp(-((x -4)^2+(y-4)^2)^2)      >:D

El resultado de la siguiente multiplicación:
The result of the following multiplication:

A) (1+1/2) * (1+1/3) * (1+1/4) ... (1+1/109)

B) (1-1/2) * (1-1/3) * (1-1/4) ... (1-1/99)

How about you just post your homework in ONE thread instead of spamming the forum with topics?

mooman, The questios are : A and B. This is to search with google: exp(-((x-4)^2+(y-4)^2)^2/1000) + exp(-((x+4)^2+(y+4)^2)^2/1000) + 0.1exp(-((x+4)^2+(y+4)^2)^2)+0.1exp(-((x -4)^2+(y-4)^2)^2)

So. What is the result of:

(1+1/2) * (1+1/3) * (1+1/4) ... (1+1/109)

What is the result of:

(1-1/2) * (1-1/3) * (1-1/4) ... (1-1/99)

Btw, do I have to do just a thread for the logical mathematical reasoning?
Regards.

A: (1+1/2) * (1+1/3) * (1+1/4) ... (1+1/109)  = (2/2+1/2) * (3/3+1/3) * (4/4+1/4) ... (109/109+1/109) =
(3/2) * (4/3) * (5/4) ... (110/109) = (110!/2!)/109!= 110!/(109!*2!) = 110/2 = 55
B: (1-1/2) * (1-1/3) * (1-1/4) ... (1-1/99) = (2/2-1/2) * (3/3-1/3) * (4/4-1/4) ... (109/109-1/109) =
(1/2) * (2/3) * (3/4) ... (108/109) = 108!/109! = 1/109

(3/2) * (4/3) * (5/4) ... (110/109) = (110!/2!)/109!= 110!/(109!*2!) = 110/2 = 55
B: (1-1/2) * (1-1/3) * (1-1/4) ... (1-1/99) = (2/2-1/2) * (3/3-1/3) * (4/4-1/4) ... (109/109-1/109) =
(1/2) * (2/3) * (3/4) ... (108/109) = 108!/109! = 1/109
I do not understand this: (110!/2!)/109!= 110!/(109!*2!) = 110/2 = 55
Look at this I have found:

Why don't you make a thread called "Help me with my maths homework" and just post all your questions there instead of making 100 threads lol.

The final challenge will be the count how many threads he made.

mooman: (110!/2!)/109!= 110!/(109!*2!) = 110/2 = 55
I do not get why you do those divisions; more than understanding n!

It is not my homework, I do this because I want to pass the aptitude test in the university and I do not understand some exercises.
