Find all solutions in the interval [0, 2π).
cos x = sin x
x = three pi divided by four., five pi divided by four.
x = pi divided by four., seven pi divided by four.
x = three pi divided by four, seven pi divided by two
x = pi divided by four, five pi divided by four.

Best ResponseYou've already chosen the best response.2alright there is another easy way to find x values sin(x) = cos (x) in unit circle sin x = y coordinate cos (x) = x coordinate so you can replace sin (x) by y and cos (x) by x x=y now now at what angle x and y values are same ??

Best ResponseYou've already chosen the best response.2yep you can convert those two angles to radians by using this formula \[\huge\rm d \times \frac{ \pi }{ 180 }\] or you can cheat(use unit circle )
