In this question, given xt, yt is equal to c1e to the power t plus c2e to the power 2t and c1e to the power t minus 2 c2e to the power 2t.
00:24
So now, xt is equal to c1e to the power t plus c2e to the power 2t.
00:31
So this imply x dash t, that means differentiate with respect to t, it will be c1e to the power t plus 2 c2e to the power 2t.
00:43
Give this equation number 1 and its equation number 2.
00:47
Similarly, yt is equal to c1e to the power t minus 2 c2e to the power 2t.
00:55
And this imply y dash t is equal to c1e to the power t minus 4 c2e to the power 2t.
01:04
Give this equation number 3 and its equation number 4.
01:09
Now xt minus yt is equal to c1e to the power t plus c2e to the power 2t minus c1e to the power t plus 2 c2e to the power 2t.
01:27
And this imply c1e to the power t will be cancel out and its 3 c2e to the power 2t.
01:38
So from here, c2e to the power 2t is equal to xt minus yt divided by, give this equation number 5...
