Category: Differential Equations

"Published in Newark, California, USA"

Find the particular solution for


in which y = 6 when x = 0.

Solution:

Consider the given equation above  


In order to separate dx and dy from other variables, divide both sides of the equation by (y - 2) cot x as follows





Integrate both sides of the equation, we have  





Take the inverse natural logarithm on both sides of the equation, we have




Substitute the value of x and y in order to get the value of C as follows





Therefore, the particular solution is
