5.2 sin (45(x + 8°)) - 1 = -3,解x,答案用度表示
2 sin (45(x + 8°)) - 1 = -3
2 sin (45(x + 8°)) = -3+1
sin (45x + 360°) = -2÷2
sin (45x) = -1
45x=270º+k*360º　（K∈Z)
x=(270º+k*360º)÷45
x=6º+k*8º （K∈Z)

2 sin (45(x + 8°)) - 1 = -3
2 sin (45(x + 8°)) =-2
sin (45(x + 8°))= - 1
45(x + 8°)=k×360°+270°
x+8°=k×8°+6°
x=k×8°+6°-8°
x=k×8°-2°是5.2不是25.2sin (45(x + 8°)) - 1 = -3
