#### If Tan^2(t)-Sin^2(t)=Sin^a(t)/Cos^b(t), then the positive power a= ALSO the positive power b=

So, I know the first two stepssin^2(t)/cos^2(t) -sin^2(t)sin^2(t)-sin^2(t)cos^2(t)/(cos^2(t)I have no idea what to do after this? I looked and it said to factor but I have no idea why you factor... more
