Hi there,
Prove that tant=sin2t÷(1+cos2t)
tant = 2sintcost/1 + (2cos^2t -1)
Convert sin2t - 2sintcost
Convert cos2t - 2cos^2t - 1
tant = 2sintcost/1+(2cos^2t - 1)
Sort out brackets
tant = 2sintcost/2cos^2t
Cancel out 2 top and bottom
Cancel out cost top and one of cost at bottom
tant = sint/cost
Hope this helps:-)
