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

Examine the following identity verification: a) identify the error and explain why it is a problem b) correctly verify the identity
tan (θ+ pi/2)= (tan θ + tan pi/2)/(1-tan θ tan pi/2)= (((tanθ)/(tan pi/2))+1)/ ((1/tan pi/2) -tan θ)= (0+1)/ (0-tan θ)= 1/ -tan θ= - cot θ
