Pre Calc HELP!

Answer 1

Use basic identities to simplify the expression.

Answer 2

??????????

Answer 3

\[\cos2x/\sin2x +(1/sinx)*sinx\]
(cos2x/sin2x)+1
(cos2x+sin2x)/sin2x
\[(\cos^2x-\sin^2x +2 \sin x \cos x)/ 2sinxcosx\]
\[(\cos^2x/2sinxcosx)-(\sin^2x/2sinx cosx)+(2sinxcosx/2sinxcosx)\]
\[(cosx/2sinx)-(sinx/2cosx)+1\]

cosx/sinx= cot x
sinx/cosx=tanx
\[((cotx-sinx)/2)+1\] this is your answer

Answer 4

thats not a choice -.-
