1 - cos^2 x = 0 , for 0 ≤ x ≤ 270°
cos^2 x = 1
cos x = ± 1
now look at the cosine curve.
Where is the y equal to either +1 or -1 within your domain ?
please what is the answer to this f math question......1-cos^2X=0 for 0°less dan equals X..then X less dan equals 270

1 - cos ^ 2 x = sin ^ 2 x
1 - cos ^ 2 x = 0 mean:
sin ^ 2 x = 0
take square root of both sides:
sin x = 0
On interval 0 ≤ x ≤ 270°
sin x = 0 only for x = 0
1 - cos ^ 2 x = 0 mean:

On interval 0 ≤ x ≤ 270°
sin x = 0 only for x = 0
Correction.
On interval 0 ≤ x ≤ 270°
sin x = 0 only for x = 0 and x = 180°
On interval 0 ≤ x ≤ 270°
sin x = 0 only for x = 0 and x = 180°
