Although changes result from business transactions, the equality of the fundamental bookkeeping equation must remain. t/f

The product of two negative rational numbers is always zero sometimes zero never zero

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
