Answer:
sec(16π/9) ≈ -1.46
Explanation:
We can use a calculator to compute the value of sec(16π/9).
On most calculators, we need to ensure that the calculator is set to radians mode. Then, we can enter the expression sec(16π/9) and evaluate it.
Using a calculator, we get:
sec(16π/9) ≈ -1.46
Rounding this to two decimal places, we get:
sec(16π/9) ≈ -1.46
