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.00≤θ<2Π sorry correction, it has to be between this interval

Best ResponseYou've already chosen the best response.0with a little bit of work you will find the solution

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.0well 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.1The answer is 0 but I used trial and error

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.0the 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.0if 2pi is excluded of course

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