A new provision of students' glossary has been made in the Advanced Learning System. Students are free to add the forumlae, teminologies and definitions as they see fit. This way a large data may be compiled from collaborative effort that may be helpful to all the students for various purposes.
If the sum of the coefficients in the expansion of $(x+y)^n$ is 4096, then the greatest coefficient in the expansion is _ _ _ _ . Solution $C_0 + C_1 + C_2 + C_3 + ......................... + C_n =4096 $ $\therefore 2^n = 4096 =2^{12} $ $\Rightarrow n = 12 $ Greatest coefficient = ${}^{12}{C_6} = 924$
