Answer:
Step-by-step explanation:
Given
The given equation is a differential equation
By separating variable
⇒
Now by taking integration both side
⇒
Where C is the constant
from above equation we can say that
When t will increases in positive direction then will decreases it means that
will increases, so y will decreases. Similarly in the case of negative t.
