Can someone help me with a few simple problems:
These 0's have lines through them, and are slanted. I used 0\ to represent that.
1.) If sin0\ = 3/5 and 0\ is in quadrant II, find sin 2(0\). (Hint: sin 2(0\) = 2 sin 0\ cos 0\)?
2.) The trigonometric expression, sin 0\(cot 0\ + tan 0\), is equilvalent to which of the following?
(A) sec(0\)
(B) sin(0\)
(C) 1
(D) sin^2(0\)
(E) csc(0\)
3.) The trigonometric expression, sin 0\ + cot 0\ cos 0\, is equivalent to which of the following?
(A) sec 0\
(B) csc 0\
(C) 2 sin 0\
(D) 1
(E) cos^2(0\)
Thanks for your help!
