Review the proof (not in order) of the identitysine (startfraction x over 2 endfraction) = plus-or-minus startroot startfraction 1 minus cosine (x) over 2 endfraction endroot. A 2-column table with 5 rows. Column 1 is labeled step with entries 1, 2, 3, 4, 5. Column 2 is labeled statement with entries sine squared (startfraction x over 2 endfraction) = startfraction cosecant (x) minus cotangent (x) over 2 cosecant (x) endfraction, sine squared (startfraction x over 2 endfraction) = startstartfraction startfraction 1 minus cosine (x) over sine (x) endfraction overover startfraction 2 over sine (x) endfraction endendfraction, sine squared (startfraction x over 2 endfraction) = startfraction 1 minus cosine (x) over 2 endfraction, sine squared (startfraction x over 2 endfraction) = startstartfraction startfraction 1 over sine (x) endfraction minus startfraction cosine (x) over sine (x) endfraction overover startfraction 2 over sine (x) endfraction endendfraction, sine (startfraction x over 2 endfraction) = plus-or-minus startroot startfraction 1 minus cosine (x) over 2 endfraction endroot. What is the correct sequence of steps? 1-2-3-4-5 1-2-4-3-5 1-4-2-3-5 1-4-3-2-5.
