The equation is
sin?/(1-cos? )-(1+cos?)/sin? = 0
sin?/(1-cos? )*(1+cos?)/(1+cos? )=(sin? (1+cos?))/(1-cos^2? )
(sin? (1+cos?))/sin^2? =(1+cos?)/sin?
(1+cos?)/sin? -(1+cos?)/sin? =0
The part that I am confused about is the *(1+cos?)/(1+cos? ). I need to justify that 1+cos? does not equal 0, because you can not divide by 0. What is the proof that goes with that part of the equation.
Thanks, Shelly
