I am currently working a physics problem and I have run into some math that I don't understand.
y = 4.0m + 4.0m(sin theta) = 4.0m(1+sin(theta))
In the problem I am trying to find a specific height at a certain angle (pendulum problem). I have found some help online that walks me through each step of the problem. I am just trying to understand how the above equation works, specifically the last part how 4 + 4(sin (theta)) is somehow equivalent to 4(1+sin(theta)). Is this some application of a formula or simple algebra that I am not understanding?
Maybe if you need more info you could check out the problem if you want too. The problem is located here: http://iweb.tntech.edu/murdock/books/v1chap6.pdf (Scroll down to page 143, worked examples # 6.2)
