Which sum or difference identity would you use to verify that cos (180° - ∅) = -cos ∅? a. sin (α -β) = sin α cos β – cos α sin β b. cos (α -β) = cos α cos β – sin α sin β c. cos (α -β) = cos α cos β + sin α sin β d. sin (α + β) = sin α cos β + cos α sin β

In triangle opq right angled at p op=7cm,oq-pq=1 determine the values of sinq and cosq

Simply 8x squared + 5(7x squared- x) - 2x =
