In this question, we have been given the differential equation that is y dash equals to 2 times t minus the root of t square minus y.
00:11
We have to verify that y1 equals to 2t minus 1 and y2 equals to t square.
00:19
They are the solution of the given equation.
00:25
Let's call this equation as equation star.
00:28
Star.
00:29
Okay, so for first y1 which is 2t minus 1, we try to find the derivative which comes out to be 2 here.
00:41
Next, what we can do, this is our left hand side.
00:47
Now we find the right hand side which is 2 times t minus root of t square minus y1 we get.
00:56
This comes out to to be t minus root of t square minus y1.
01:01
It becomes minus 2t plus 1.
01:04
This is t minus root of t minus 1 whole square.
01:10
This comes out to be 2 times t minus t minus 1.
01:15
So t and t gets cancelled.
01:16
We are having 2...
