7sin²(x)  14sin(x) + 2 = 5 7sin²(x)  14sin(x) + 7 = 0 7(sin²(x)  2sin(x) + 1) = 0 sin²(x)  2sin(x) + 1 = 0 (sin(x)  1)² = 0 sin(x)  1 = 0 sin(x) = 1 x = 90°

then sin x=1 is correct. but do u need solutions in the range of 0 to 180 only or all solutions ?

no idea. the question say find all solutions to the equation

hartnn Group TitleBest ResponseYou've already chosen the best response.0
because sin (360+90) also =1

yes, all solutions means u don't have only 1 solution, u have infinite

alright

sin(x)=1 sin x = sin (90+360n) (n=1,2,3,....) so x= 90+360n are all the values of x with n=1,2,3,....`

idk how your teacher / system demands the answer, but any of these 2 answers are complete and correct: 1) x= 90+360n , n=1,2,3,..... 2) x=90,450,810,..
