Are the angles in radians, or degrees? Just like with all functions, the arguments should be enclosed in parentheses.

1. Cohen did not enclose the arguments in parentheses.

2. There is a picture to be used with this question(s).

3. In terms of radians or degrees, I have to check the textbook again.

1. Suppose you type sin x + 2. I don't know whether you mean sin(x) + 2 or sin(x + 2). Parentheses removes that ambiguity and is why it is considered good form.

Ok. Let me try to upload the related picture.

I could not upload the given circle picture here. So, we will skip all Larger Trig Quantity threads.
