  • anonymous
cuz i understand if u cant
Nnesha
  • Nnesha
yeah i'm going to help you i just wanted to make sure that equation is correct :-)

alright i can retype it. it's cos x = sin x :-D
Nnesha
  • Nnesha
alright set it equal to one divide both sides by cos
anonymous
  • anonymous
i dont know how to do any of this :/
anonymous
  • anonymous
i'm so sorry

alright 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 ??

45 degrees

  • Nnesha
yes there is one more !

and 225 degrees

  • Nnesha
yep 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 )
