1 – sin260
By using sin²+cos² = 1, I figured;
1 – sin²60 = cos²60
Do I continue with the question or is that the answer? I’m not sure what the next step would be since its squared.
THANKYOU!!!

sin 60 = √3/2
sin^2 60 = 3/4
1-3/4 1/4.
Also cos 60 = 1/2
and (1/2)^2 = 1/4.
Thus either way of proceeding is correct.
