Can someone help me with a few simple problems:(adsbygoogle = window.adsbygoogle || []).push({});

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!
