Find the general solution for
Solution:
Consider the given equation above
Since the given equation is already arranged according to their variables, then we can integrate on both sides of the equation as follows
In this type of integration of trigonometric functions, we need to use the principles of trigonometric identities first before we can do the simple integration of trigonometric functions. Hence, the above equation becomes
Therefore, the general solution is
where D = 3C.
