Well if you must use the value of g, state what value you are using.

Re: BdMO National Higher Secondary 2014/9

Your answer is right, but you have to prove this yourself. Just stating that it's a case of the catalan recurrence won't work.

Re: Use of the value of $g$

As far as I know, you will be given the value of g if you require it. Can you send the question here where you think you have to use the value of g?

Re: BDMO 2017 National round Secondary 5

Ooh I got a cool solution to this. So, $OM+OB = AB$ and $MB=\dfrac{AB}{2}$. Also by pythagorean theorem, $MB^2+OM^2=OB^2$. Substituting, $\dfrac{AB^2}{4} + (AB-OB)^2 = OB^2$ Or, $\dfrac{AB^2}{4} + AB^2 - 2\times AB \times OB + OB^2 = OB^2$ Or, $\dfrac{AB^2}{4} + AB^2 - 2\times AB \times OB = 0$ Or, ...
