Question 921858: Find the solution set of each of the following over the interval 0 ≤ x < 2.
1) sin x - 1= 0
2) √2 cos x + 1= 0
3) tan^2 x - 1= 0

1)sin x-1 =0
add 1 on both sides
sin x-1+1 =0+1
sinx = 1

x =
2) cos *x +1=0
subtract 1 on both sides
cos *x +1-1 =0-1
cos *x =-1
divide with on both sides
*cos *x =-1*
cos *x =
x = 3π/4
3)
tan^2 x -1 =0
add 1 on both sides
tan^2 x-1+1=0+1
tan^2 x =1
square root on both sides
sqrt(tan^2 x ) =
tan x= 1
x = π/4
