00:01
So, here we are given the equation which is y double dash minus 20, y dash plus 100 of y is equal to, this is equals to e raised to the power minus 10 of x divided by a 1 plus x square, where y of 0 is equal to 5 and y dash of 0 is equals to minus 5.
00:21
So we have to find out the solution of this equation.
00:24
So the auxiliary form of the equation, auxiliary form will be r square minus 20 r plus 100 is equal to 0.
00:38
So we can write it as r minus 10 whole square is equal to 0.
00:42
So from here we get the roots of the equation 10 and 10.
00:46
So we can say that the y n of x is equal to c1, e raised to the power 10 of x plus c2 x, e raise to the power 10 of x.
00:55
So this is the solution of this equation.
01:00
Now in the second part, we have to find out the value of where we are given that y is equal to e1, e10 raised to the power x.
01:11
And y2 is equal to x, e raised to the power 10 of x.
01:14
So here we have to find it's general assumption.
01:17
So yp is equal to y1 x, u1, x plus y2x, y2x, plus y2 x, u2x, u2x, u2, u.
01:29
U2x.
01:30
So from here we can say that u1 dash is equals to minus y2, k of x divided by the w of x and u2 dash will be y1, r of x divided by the w of x.
01:45
Let's say this is the equation number 1.
01:47
So from here we can say that r of x is right hand side of given equation...
