The graph theory HELP! How many distinct graphs can be found by the set V={1,2,...,n} with k edges? For this question i conclude that totao.l number of distinct graphs comes with 2^(choose two in n) but i cannot find the solution which gives the relation with k edges can you help me?

Can i define a sequence which starts with a2. term or i must define the first term a1 as well

yes:) but there is a x before the integral

lim x \int cost / t^2 (integral x to 1) x goes infitine

\int (((ax^2)/(x^3)+5) + 2 / x^3) dx (one to infinite integral) find the all possible values of a?

i have no sense to solve it i just know answer is 2^(2n-1) + 2^n -1

a "codeword" from the alphabet A={0,1,2,3) is said to be legitimate if it contains even number of zeros. Thus for instance the codeword 31020 is legitimated and 0002 is not. How many n - letter codewords are legitimated ?

Find all continuous functions f(x) satisfying f(x) > −1 and f(x) = x + \int_{1}^{x} f(t) dt for all x

Yes i mean this integral

So i did it but how can i provide the result by this way

Find all continuous functions f(x) satisfying f(x)>1 and f(x) = x +(1 to x integral) \int f(t).dt for all x

lim (e^((x^3)*tan1/x))/e^(x^2) x goes infinite

I have some questıons about aolıcatıons of ıntegral can you help me?
