Question

Compute the following angles using your calculator or the online calculator C. (Use the AC button to clear computations). In all cases, round your answer to three decimal places. C) cos( - 1.05) d) sin(160.2°)

Answer 1

To compute the given angles using a calculator or online calculator C, follow these steps.

C) cos(-1.05) = 0.548

D) sin(160.2°) = 0.997

Step-by-step explanation:

C) cos(-1.05) = 0.548

To compute the cosine of -1.05, enter -1.05 on your calculator and press the cos button. The result rounded to three decimal places is 0.548.

D) sin(160.2°) = 0.997

To compute the sine of 160.2°, enter 160.2 on your calculator and press the sin button. The result rounded to three decimal places is 0.997.
