Best ResponseYou've already chosen the best response.0these are the directionsSolve the given equation. (Enter your answers as a commaseparated list. Let k be any integer. Round terms to two decimal places where appropriate.)

Best ResponseYou've already chosen the best response.1There is an infinite amount of solutions, you need to write it in a way to GENERALIZE the solution.

Best ResponseYou've already chosen the best response.2so let me generalize it. cos function is periodic with 2pi. so values repeat after every 2pi*k here, \(\theta =\pm(3\pi/4+2\pi k),\pm(5\pi/4+2\pi k)\)

Best ResponseYou've already chosen the best response.0ohh i see but why do u add the 2pik at the end ? because it is a periodic function?

Best ResponseYou've already chosen the best response.2yes, as i said cos function is periodic with 2pi. so if a is solution, so is a+2pi, a2pi,a+4pi,a4pi, and so on
