在第一象限中找出三角函数值与之相等的角，并使用这一参考角。 令表达式取负值，因为正切在第二象限为负。 sec(45) sec (45) 的准确值为 2 √2 2 2。 将 2 √2 2 2 乘以 √2 √2 2 2。 合并和化 …

sec is found using Hypotenuse/Adjacent. sin is positive. 135 > 90°, so it is obtuse. sec (135) = -√ 2.

What is the exact value of sec(135°) in simplest rationalized form? \displaystyle\sqrt { {2}} Explanation: Trig table, unit circle, and property of complementary arcs --> \displaystyle {\cos { …

The sec of 135 degrees is -√2, the same as sec of 135 degrees in radians. To obtain 135 degrees in radian multiply 135° by $\pi$ / 180° = 3/4 $\pi$. Sec 135degrees = sec (3/4 × $\pi)$.

What is the value of sec (135) ?

In this lesson, we explored the concept of sec 135 degrees in trigonometry. We reviewed the definitions of sine, cosine, and tangent functions and their ratios in a right triangle. Secant, …
