Question

value of sec theta or cosec theta is always greater than or equal to how much​

Answer 1

Answer:

secA=cosecB

when

the sum of A+B is equal to 90degree

sec30=cosec60

30=60

45=45

Answer 2

The value of $\sec \theta$ or $\csc \theta$ is always greater than or equal to - (infinity).

Step-by-step explanation:

The range of the functions $f(\theta) = \sin \theta$ or $f(\theta) = \cos \theta$ is [-1, 1].

That means the value of $\sin \theta$ or $\cos \theta$ lies between - 1 to 1 for all real value of $\theta$.

Therefore, the functions $f(\theta) = \sec \theta$ or $f(\theta) = \csc \theta$ ranges between - ∞ to + ∞.

{Because $\csc \theta = \frac{1}{\sin \theta}$ and $\sec \theta = \frac{1}{\cos \theta}$ }

Therefore, the value of $\sec \theta$ or $\csc \theta$ is always greater than or equal to - (infinity). (Answer)
