if y=a cos(logx)+bsin(logx) then show that x' !,n, r (2n -rl)xy,*, + (n2 +1)-y,, = 0

(6p+1)/3 +1=7p-3/2

alpha/bita^2 + bita/alpha^2 = alpha^3+bita3/(alpha.bita)^2

if y=a cos(logx)+bsin(logx) then show that x' !,n, r (2n -rl)xy,*, + (n2 +1)-y,, = 0

Here is the doubt. The 3 friends get the watch for 9 Rs. 9 * 3 is 27 plus the 2 Rs = 29 RS where is the 1 Rsplz soive it

1,28,92,217,433,776,?

(a)924 (b)1148

(c)1288 (d)1304

and how?

ax^2 +(a+b)x +b=0 is necessarily true?

(I) It has atleast one negative root.

(II) It has atleast one positive root.

(III) Both its roots are real.

A. I and II only

B.I amd III only

C.II and III only

D.All of them

^{1/2}/2 A from mean position its kinetic energy gets increased by an amount 1/2 mw^{2}A^{2}due to an impulsive force. Then it's new amplitude becomes what?(6p+1)/3 +1=7p-3/2
