Web1- [cosX squared/1 +sinX] = [1 + sinX - (cosX)^2]/1 + sinX This is possible because 1 = (1 + sinX)/ (1 + sinX) We also know that 1 - (cosX)^2 = (sinX)^2 Now, [1 - (cosX)^2 + sinX]/1 + sinX = [ (sinX)^2 + sinX]/1 + sinX Factoring out the sinX, [sinX (sinX + 1)]/1 + sinX = [sinX (1 + sinX)]/1 + sinX = sinX Hope this helped!
