Giải phương trình $\sin 2x = \pm 1$.

Sin 2x is a trigonometric formula in trigonometry that is used to solve various trigonometric, integration, and differentiation problems. Use the basic trigonometric identity: csc(x)= sin(x) 1 =1+ sin(x) 1 ⋅ 2 1 sec(x) Use the basic trigonometric identity: sec(x)= cos(x) 1 =1 at x=1.5 y = = 1/2-3 7/½.
