Re: Problem in Finding the sum of series
2nd prob:if x is a real number ,there might be many solns,but if $$x\in R$$,there is no soln $$\geq3$$

Re: An Interesting problem
there are no solutions because the sum of $$n$$ integers $$\geq2$$ can not be equal to both their product and $$n$$.
If 1 of the conditions are removed,there might be a solution

Re: \tan law
here's another moderation:
$$tan A=\frac{4\Delta}{b^2+c^2-a^2}$$
P.S.moderated by Sakal Roy.

\tan law
this is quite embarrassing:
$$\tan A= \frac{abc}{R(b^2+c^2-a^2)}$$
has this already been invented?if not(possibility of not being invented is tends to 0),will i get a patent ?
