Convert each degree measure to radian measure. Ex- press the answer in terms of \( \pi \) and as a decimal approxi- mation rounded to the nearest hundredth. \( \begin{array}{ll}\text { 9. } 35^{\circ} & \text { 10. }-40^{\circ} \\ \begin{array}{ll}\text { 11. } 1080^{\circ} & \text { 12. } 154.5^{\circ} \\ \text { Convert each radian measure to degrees. Round an- } \\ \text { swers to the nearest tenth of a degree if necessary. } \\ \begin{array}{ll}\text { 13. } \frac{\pi}{5} & \text { 14. }-\frac{7 \pi}{2} \\ \text { 15. } \frac{\pi}{12} & 16.5\end{array}\end{array} .\end{array} \).

(d) Quando fazemos determinaçōes experimentais de uma grandeza \( X \), representamos seu valor numérico final acompanhado do erro \( \Delta X \) associado à medida, na forma \( X \pm \Delta X \). Para calcularmos o valor de uma funçāo \( f(X \pm \Delta X) \), utilizamos a regra \[ f(X \pm \Delta X)=f(X) \pm f^{\prime}(X) \Delta X \] Obtenha as fórmulas referentes a (i) \( \sin (X \pm \Delta X) \) e (ii) \( \cos (X \pm \Delta X) \)
