En los ejercicios 1 a 5 encuentre las soluciones de la ecuación en el intervalo \( 0^{\circ} \leq \theta \leq 360^{\circ} \) 1. \( \operatorname{sen} \theta=\frac{\sqrt{3}}{2} \) 2. \( \cos \theta-1=0 \) 3. \( \tan \theta+\sqrt{3}=0 \) 4. \( \sec \theta-\sqrt{2}=0 \) 5. \( \cot \theta=-1 \)

\( \csc 82.4^{\circ}= \) Blank 1 Express your answer in 3 decimal points.

\( r = \tan \theta \sec \theta \)

(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) \( \cos (X \pm \Delta X) \)

tan \( 0.8035=\underline{\text { Blank } 1} \) (Express your answer in 3 decimal points) Blank 1 Add your Thnswer

\( \left(\sec 79.36^{\circ}\right)\left(\sin 79.36^{\circ}\right)-\left(\tan 79.36^{\circ}\right)=\underline{\text { Blank } 1} \)
