In this question here we have given that sorry cube y s is equals to 0.
00:35
Here we are using the initial condition which is the x 0 equals to 0 and y 0 equals to 0 here y dash 0 equals to 0 and y double dash 0 equals to 0.
00:50
We can simplify the equation as follows.
00:54
First equation is s minus 4 x s plus s cube y s equals to 18 by s square plus 1 and second one is s plus 2 x s minus 2 s cube y s is equals to 0.
01:17
Here now we are solving the equation for x s and y s.
01:21
First let solving the equation 1 from equation 1 sorry 2 for 4 x s here x s is equals to 2 s square by s plus 2 y s.
01:44
Here we are substituting the expression of x s in equation 1 then we have s minus 4 2 s cube by s plus 2 y here this is cube y s here just a second plus s cube y s is equals to 18 by s square plus 1.
02:13
So here we are solving solve for the solve for y s.
02:21
So here the s minus 4 2 s cube by s plus 2 plus s cube multiply by s is equals to 18 by s square plus 1.
02:37
So here we have the y s is equals to 18 divided by s plus 1 s plus 2 multiply s square minus 2 s minus 1.
02:51
Here first let find the roots of the this quadratic equation which is s is equals to here s square minus 2 s minus 1...
