Best ResponseYou've already chosen the best response.0sin^2(theta) can be written as 1cos^2(theta) and guess what that can be factored

Best ResponseYou've already chosen the best response.0Use the identity below (solved for \(\sin^2 \theta\)) \(\sin^2 \theta + \cos^2 \theta = 1\) and do a substitution in the numerator. Then factor the numerator and reduce.

Best ResponseYou've already chosen the best response.0=(1cosθ)(1+cosθ)/(1+cosθ) then we simplfy we know that a^2  b^2=(ab)(a+b) @Madgirlwithabluebox

Best ResponseYou've already chosen the best response.0so we get after simplifying the result =(1cosθ) did u understand @Madgirlwithabluebox

Best ResponseYou've already chosen the best response.0Uh no? I get that since there was (1+cosθ)/(1+cosθ) you simplified and got the answer but i dont understand anything else

Best ResponseYou've already chosen the best response.0does this make sense: assuming y not 1 simplifying (1y^2)/(1+y) \[\frac{1y^2}{1+y}=\frac{(1y)(1+y)}{1+y}=\frac{\cancel{(1+y)}(1y)}{\cancel{1+y}}=1y\]
