The trigonometric functions \(\displaystyle{\sec{{\left({135}^{\circ}\right)}}}\)

Answers (1)

To find the value of the trigonometric functions, first, convert sec function in terms of \(\displaystyle{\cos{{\left(\theta\right)}}}\).
Use the identity \(\displaystyle{\sec{{\left(\theta\right)}}}=\frac{{1}}{{{\cos{{\left(\theta\right)}}}}}\)
We have
Now \(\displaystyle{\sec{{\left(\theta\right)}}}=\frac{{1}}{{{\cos{{\left(\theta\right)}}}}}\)
