Answer

To find the other trigonometric functions in terms of \( \sin A \): 1. **Coseno (\( \cos A \))**: \[ \cos A = \sqrt{1 - \sin^2 A} \] 2. **Tangente (\( \tan A \))**: \[ \tan A = \frac{\sin A}{\sqrt{1 - \sin^2 A}} \] 3. **Cotangente (\( \cot A \))**: \[ \cot A = \frac{\sqrt{1 - \sin^2 A}}{\sin A} \] 4. **Secante (\( \sec A \))**: \[ \sec A = \frac{1}{\sqrt{1 - \sin^2 A}} \] 5. **Cosecante (\( \csc A \))**: \[ \csc A = \frac{1}{\sin A} \] **Notes:** - The sign of each function depends on the quadrant of angle \( A \). - Ensure that \( \sin A \neq 0 \) for \( \csc A \) and \( \tan A \) to avoid division by zero. - Consider the context or additional information about angle \( A \) to determine the correct sign.

Para calcular las funciones trigonométricas en función del seno de A, puedes usar la relación fundamental entre ellas. Si sabes que \( \sin A = y \), puedes encontrar \( \cos A \) usando la identidad pitagórica: \( \cos A = \sqrt{1 - \sin^2 A} \). Dirígete a las funciones restantes: \( \tan A = \frac{\sin A}{\cos A} \), \( \csc A = \frac{1}{\sin A} \), \( \sec A = \frac{1}{\cos A} \) y \( \cot A = \frac{1}{\tan A} \). ¡Ahora tienes todas las funciones en tu bolsillo! ¡Ahora un truco útil! Asegúrate de verificar el cuadrante en el que se encuentra el ángulo A, ya que esto afectará el signo de \( \cos A \). Siempre recurre a un círculo unitario: si \( \sin A \) es positivo, pero \( \cos A \) es negativo, tu tangente será negativa. ¡Es un pequeño detalle que puede marcar la diferencia en tus cálculos!
