Question1. Find sin83\sin 83^{\circ}.
2. Find cos10.47\cos^{-1} 0.47.
3. Find tan16\tan 16^{\circ}.
4. Find cot21\cot 21^{\circ}.
5. Find sin10.40\sin^{-1} 0.40.

Studdy Solution
Use a calculator to find the approximate value of sin0.40\sin ^{-}0.40.
The solutions to these problems will depend on the calculator used, as different calculators may give slightly different results due to rounding and precision. However, the solutions should be approximately. sin830.99\sin83^{\circ} \approx0.99 . cos0.4762\cos ^{-}0.47 \approx62^{\circ}
3. tan160.29\tan16^{\circ} \approx0.29
4. cot21.74\cot21^{\circ} \approx.74
5. sin0.4024\sin ^{-}0.40 \approx24^{\circ}
