Question

evaluate

sec(1.7

Answer 1

[AI-generated answer — Explain Bot]

To evaluate sec(1.7), you can use a scientific calculator or a trigonometric table.

If you don't have access to a calculator or table, you can use the reciprocal identity of secant to find the value. The reciprocal identity states that sec(x) is equal to 1/cos(x).

So, to evaluate sec(1.7), you need to find the value of cos(1.7) and then take its reciprocal.

If you have a scientific calculator:

1. Make sure the calculator is set to radians mode (most calculators default to radians).
2. Enter 1.7.
3. Press the cos function key to find cos(1.7).
4. Then press the reciprocal (1/x or 1÷x) key to find the reciprocal of cos(1.7). This will give you sec(1.7).

If you don't have a scientific calculator, you can use online trigonometric calculators or trigonometric tables available on the internet. These tools can help you find the value of cos(1.7) and then calculate the reciprocal.

Keep in mind that sec(x) is undefined for certain values of x, such as x = 0 or x = π/2 (90 degrees), where cosine is zero.
