Best ResponseYou've already chosen the best response.1When in doubt, draw a sketch: dw:1357770541986:dw The sketch is for 0<=x <=2pi. The general solution requires the form x=.... +2k pi where k is an integer.

Best ResponseYou've already chosen the best response.1You will need to solve for sin(x)=cos(x) between 0 and 2pi. The same solution will be valid if you add 2k pi to the obtained solution. Are you able to find the solution between 0 and 2pi?

Best ResponseYou've already chosen the best response.0i dont have a answer like that it is just pi/4 +2npi and 7pi /4 + 2npi. the answer with 5pi/4 + 2npi is paired with 3pi/4 + 2npi

Best ResponseYou've already chosen the best response.1I don't know what the question is exactly but the solution to sinx=cosx is definitely x=pi/4 +2npi and x=5pi/4 + 2npi
