AI Thread Summary
To solve for theta in the equation √13 Sin(θ-56.31)=1 within the interval 0<θ<360, the first step is to isolate sin(θ - 56.31) as 1/√13. This leads to two potential solutions: θ = 72.412 and θ = 163.898. The discussion highlights that there are infinitely many solutions due to the periodic nature of the sine function, which repeats every 360 degrees. The conversation emphasizes the importance of considering the specified interval to limit the solutions. Understanding the periodicity of sine is crucial for finding all possible values of theta.

Homework Statement



How do I solve for theta here:

√13 Sin(θ-56.31)=1 in the interval 0< θ <360

2. The attempt at a solution
sin (θ - 56.31) = 1/√13
sin (θ - 56.31) = sin ( 16.102 )
=> θ - 56.31 = 16.102
Hence θ = 72.412
or θ - 56.31 = 180 - 16.102
θ - 56.31 = 163.898

Yes that's correct. You had one line left to go, why did you stop? :-p

And this is assuming there is an interval for \theta such as 0&lt;\theta&lt;360^o because then you'll have an infinite number of solutions.
 


yes, there are an infinite number of solutions. Think about the periot of sine.
for example, f(x+2*pi)=f(x)
...f(30+(-360))=f(30)=f(30+360)=f(30+720)=...
 
I picked up this problem from the Schaum's series book titled "College Mathematics" by Ayres/Schmidt. It is a solved problem in the book. But what surprised me was that the solution to this problem was given in one line without any explanation. I could, therefore, not understand how the given one-line solution was reached. The one-line solution in the book says: The equation is ##x \cos{\omega} +y \sin{\omega} - 5 = 0##, ##\omega## being the parameter. From my side, the only thing I could...
