sec(360)<= θ<= 360

解答

sec^{\circ} (36 0^{\circ}) \leq θ \leq 360

sec^{\circ} (36 0^{\circ}) \leq θ \leq 360

间隔符号

[sec^{\circ} (36 0^{\circ}), 360]

十进制

0.01745 \dots \leq θ \leq 360

求解步骤

sec^{\circ} (36 0^{\circ}) \leq θ \leq 360

无法进一步化简

sec^{\circ} (36 0^{\circ}) \leq θ \leq 360

- 1 < \frac{0.2}{4 \cdot cos ^{2} ( x ) - 3} < 0

- 18 0^{\circ} < tan (x) < 18 0^{\circ}

sin (θ) < 0 and sec (θ) > 0

cos (θ) = \frac{3}{4} and cot (θ) < 0

sin (θ) > 0 and cos (θ) > 0
