Split the single integral into multiple integrals. Lấy nghịch đảo sin của cả hai vế của phương trình để trích xuất từ trong hàm sin. This means we are looking for all the angles, x, in.
The Principal Solutions Of Sin(X).
We have a formula in trigonometry which says that. Sin(x) = 1 2 sin ( x) = 1 2. X = arcsin(1 2) x = arcsin ( 1 2) simplify the right.
