Best ResponseYou've already chosen the best response.1can theta=0 ? Like is is\[ 0< \theta <\Pi\] Or \[ 0 \leq \theta \leq \Pi\] ?

Best ResponseYou've already chosen the best response.00<θ<2Π has to be between this interval

Best ResponseYou've already chosen the best response.0@Mertsj what about if they have a log like for example using the graph solve the system y=2x+3 and y=logx+1 im confused cause of the log

Best ResponseYou've already chosen the best response.0@RED123url I am not sure what you did there...

Best ResponseYou've already chosen the best response.1well y=tan(theta/2) sin(thata)= 2y/(y^2+1) cos(theta)=(1y^2)/(y^2+1) you know tan=sin/cos sec=1/cos plug things in and you will get an equation of y then go back y=tan)theta/2) and use the inverse

Best ResponseYou've already chosen the best response.0@RED123url so just to confirm what swissgirl got, did you get the same answer?

Best ResponseYou've already chosen the best response.1Well it is 0 and 2 pi But if you noticed the interval is \[ 0 \leq \theta < 2\pi \]

Best ResponseYou've already chosen the best response.0@RED123url well 2pi is not one the answers but 0 is, also according to the interval 2pi cannot be the answer..

Best ResponseYou've already chosen the best response.1the real answer for these kind of problem involves n: the answer is 2npi. n can be 0 or any number even a billion

Best ResponseYou've already chosen the best response.0@RED123url so would you agree that in this case the answer is 0?

Best ResponseYou've already chosen the best response.0well then. I am going with 0. Thank you both for your help!
