度数

x = 6 0^{\circ}, x = 12 0^{\circ}, x = 42 0^{\circ}, x = 48 0^{\circ}, x = 78 0^{\circ}, x = 84 0^{\circ}, x = 114 0^{\circ}, x = 120 0^{\circ}, x = 150 0^{\circ}, x = 156 0^{\circ}, x = - 30 0^{\circ}, x = - 24 0^{\circ}, x = - 66 0^{\circ}, x = - 60 0^{\circ}, x = - 102 0^{\circ}, x = - 96 0^{\circ}, x = - 138 0^{\circ}, x = - 132 0^{\circ}

求解步骤

9 csc (x) = 63, (- \infty, \infty)

两边除以

9

9 csc (x) = 63

两边除以

9

\frac{9 csc ( x )}{9} = \frac{6 3}{9}

化简

csc (x) = \frac{2 3}{3}

csc (x) = \frac{2 3}{3}

csc (x) = \frac{2 3}{3}
