I have this question that is bugging me to death. Ok here it is:
If a coin was flipped a maxium number times of five. What is the expected value for the number of flips required to get either 3 heads or 3 tails.
I know the probability of head or...
Hello
can someone please give me some advice on applying the area of a surface revolution. I never seem to plugin the right formula.
In the formula S(from a to b) 2pi f(x)**sqrt(1 + f'(x)^2) I never know what to put for f(x)** some times the answers have just x and sometime it has the...
Thanks for your response.
When you say add K^2 + 2k to both side are you added it to 1 < k? How do you know to use 1 < k?
where does the 3k < k^2 come from?? and where does (k+1)^2 < 2k^2 < 2*2^k come from??
Thanks. I have updated this statement (k+1)^2 = k^2 + 2k + 1 < k^2 + k + 1 = k^2 + 2k + k < k^2 + 3k < K^2 + k^2 (Since k > 3).
Sorry.
This is actually the part that I start to get confused on. (k+1)^2 = k^2 + 2k + 1 < k^2 + k + 1 = k^2 + 2k + k < k^2 + 3k < K^2 + k^2 (Since k > 3)...
I have this question in my text that I can not understand
here it is
Show that 2^n > n^2 whenever n is an integer > 4.
the part in the answer that is confusing me is the inductive step
Here is what the text has for this part of the answer
Now we assume the induction hypothesis...
Hello Members
I am having a little bit of a problem solving this proof for my Discreet math course.
If g and f o g are onto(Surjective), is f onto(Surjective)? Need to prove. I believe that f has to be Onto.
so I have g: A -> B
f: B -> C
Well I understand that a...
