SOLUTION: 1+sin3x= cos(x/4) x belongs to [0,pi]

Question 893888: 1+sin3x= cos(x/4) x belongs to [0,pi]
Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
the easiest way to solve this is by graphing.

the first graph is in degrees.
the second graph is in radians.

the solution is the intersection of the two graphs.

since you are talking radians, i'll talk radians.
refer to the second graph.

the solution in the interval between 0 and pi is:

x = 0
x = 1.059 radians
x = 2.051 radians

i wasn't able to figure it out without graphing and i ran out of time to even try to figure it out.

hopefully the graphing solution will help you to find the answer, or at least to indicate where your potential solutions lie.
