Hi, I need to prove:
(tan y + Cot y) sin y cos y = 1
I've gotten this far and got stuck:
(tany + cos y) sin y cos y changed Cot to reciprical
--------sin y
(sin y tany + cosy) sin y cos y common demonator
--------siny
(sin y tany + cos y) cosy multipyied by sin y
then i could distribute
cos y sin y tan y + cos(sqared) y but how would that equal 1?
thanks for your time.
