Si el seno de un ángulo es \( \frac{3}{5} \), ¿cuál es el valor de su cosecante?

Define la función cotangente en términos de un triángulo rectángulo.

Explique como a secante se relaciona com o cosseno e forneça uma fórmula que utilize essa relação.

In the context of a right triangle, if the cosine of an angle measures \(0.6\), what can you infer about the ratio of the lengths of the adjacent side to the hypotenuse?

Read the instructions carefully and attempt the In \( \triangle \mathrm{PQR}, \angle \mathrm{P}=90^{\circ}, \angle=30^{\circ}, \mathrm{PQ}=2 \mathrm{~cm} \). \( \begin{array}{ll}\text { Find } & \begin{array}{ll}\text { a. }\end{array} \mathrm{Q} \\ \text { b. Find the length } \mathrm{QR}\end{array} \)

2. \( \operatorname{Sin}\left(90^{\circ}+y\right) \).
