Cosθ=3/2
√99以上 cos x=-√3/2 292189-Cos(x+3/2pi)
so sin (11x)cos (6x)cos (11x)sin (6x)=√3/2 sin (11x 6x) = √3/2 sin 5x = √3/2 5x = 60° or 1° x = 15 or 24° the period of sin 5x = 360/5° = 72° you asked for all solutions, which is not possible, since we have an infinite number of solutions, the general solution would beEach of these angles has different values with different trigonometric functions Note 1 cos theta = 1 Cos θ; The delta or mesh connection (Δ) system is also known as the threephase threewire system (3phase 3 wire) and is the most preferred system for AC power transmission when for distribution, a star connection is commonly used In the interconnection system delta (also denoted by Δ), the three phases or the starting end of the coil are
