1-Write the following in terms of sinx and cosx; then simplify if possible. cotxcscx

2-Write the following in terms of sinx and cosx; then simplify if possible. Your answer should only contain sinx and cosx. cscx/secx

3-Find the exact values of sin(2x), cos(2x) and tan(2x) without solving for x. If sinx=1/3, and x is in quadrant 3. sin(2x)= cos(2x)= tan(2x)
