What are the steps in solving each integration and getting each answer below? Question 1 = ?(2/L) sin2(n?/L) x2 dx By solving this integration we can find : Integration is from 0 to L; Therefore: = L2/3 - L2/(2n2?2) Question 2 = ?(2/L) sin2(n?/L) x dx By solving this integration we can find : Integration is from 0 to L; therefore: = L/2

Explanation / Answer

0->L ?(2/L) sin2(np/L) x2 dx = since x is variable here , all other variaables will act as constant (2/L) sin2(np/L) * 0->L?x2 dx (2/L) sin2(np/L) *0->L{x3/3) L2/3 - L2/(2n2p2) Q2 is same as Q1
