    Arcs Doubt in a circle.

    Greetings, I'm having a discussion with my teacher, where we got to apply the theorems of the angle inscribed in the circumference. I don't know whether it's true that the following arc PE is equally to angle A, since we got the inscribed theorem where it should be the double of the angle A...

    Algebra Pythagorean Theorem

    Hello all. I was wondering how to solve this particular problem. I am not certain I am setting it up correctly, and I think it's likely I don't have it quite right. Any help is deeply appreciated. (from textbook) "Use the Pythagorean Theorem to find the missing side length. Leave answer in...

    Real analysis rudin theorem 1.21

    In thorem 1.21 of Rudin He has said that as t=X/(X+1) then t^n<t<1 then maximum value of t is 1. then in the next part he has given that t^n<t<x. as maximum value of t is less than 1 why has he given that t<x ? X is a real number and 0<X and And n Is a integer n>0 .

    Some sort of extension to the polynomial remainder theorem?

    Two questions on another board I'd like to learn how to solve. 1) $p(x) \equiv 1 \pmod{x+1},~p(x) \equiv -7 \pmod{x+5}$ What is $p(x) \pmod{(x+1)(x+5)}$ ? 2) $x^{1000} \pmod{(x^2+1)(x+1)} = ?$

    Central Limit Theorem for weighted summation of random variables?

    Here is a quick question:- If X1, X2, X3,.... X20 are 20 random variables (independent/ idd) What would be the result of: 2*X1+5*X2+1*X3+18*X4...+0.5*X20? (linear combination of the random variables, with fixed known constants). Will the above function form a normal distribution if we...

    Sandwich Theorem Trig Funcs.

    For some reason I struggle using the sandwich theorem in solving trigonometric function limits. Example Solution But I can not understand how he does that. My try using -|θ| < sinθ < |θ| : -|2x| < sin2x < |2x| \Leftrightarrow \frac{-|2x|}{x} < \frac{sin2x}{x} < \frac{|2x|}{x} what...

    Question related with Binomial Theorem

    How can we find the index 'n' of the binomial \left ( \frac{x}{5}+\frac{2}{5} \right )^{n}, n\epsilon N if the 9th term of the expansion has numerically the greatest coefficient. Thx.

    Fermat Last Theorem Diophantine Analysis

    Analysis using Diopphantine Equations Diophantine Equations are used to remove as many variables as possible and write the remaining unknowns in terms of the other unknowns. By analyzing the remaining terms as whole numbers, we can decided whether there are infinite number of solutions or zero...

    Fermat's last theorem

    Have I found a novel way of expressing Fermat's last theorem as follows? N = nt{ K.A^(3-p)} where N is the number of primitive triples a, b, c and a^p = b^p +c^p and a all values up to A. (K is about .155, 0.152929 for p =1 and 0.159155 for p = 2) For example, this gives for a up to 10,000...

    one page proof of Fermat's Last Theorem

    I am sending you an invitation to see the one page proof of Fermat's Last Theorem. This proof uses Fermat's Right Triangle Theorem to prove the Theorem. Also included in the proof is the diagram Fermat could not include in the margin of the book. It is an amazing proof. wFyX5uqyLLA

    series vs theorem

    Hello My series is $R_3=2$ R_{n+1}=\frac{R_n}{\cos\left(\frac{\pi}{n}\right)} I will demonstrate why it is divergent. To calculate the limit from n to infinity we must first define the n, so I'm going to calculate it Can find from the formula that n = pi / arccos (Rn / (Rn + 1)) so Rn /...

    Academic Guidance A lemma which is a special case of a theorem

    It is often the case that a theorem is called using a lemma which in turn is an easy consequence of the theorem (in other words, is a special case of the theorem). Which term could you suggest specifically for such a lemma? I think about using my own coined word (like "specialia") to...
