Solution

To solve the problem, we need to compute all six trigonometric functions for θ\theta, given that cscθ=6\csc\theta = \sqrt{6} and θ\theta is an acute angle. Let's proceed step by step:


Step 1: Understanding cscθ\csc\theta

cscθ=1sinθ\csc\theta = \frac{1}{\sin\theta}.
Since cscθ=6\csc\theta = \sqrt{6}, we can find sinθ\sin\theta:
sinθ=1cscθ=16.\sin\theta = \frac{1}{\csc\theta} = \frac{1}{\sqrt{6}}.
Now, rationalize the denominator: sinθ=66.\sin\theta = \frac{\sqrt{6}}{6}.


Step 2: Pythagorean Theorem

For a right triangle, if sinθ=oppositehypotenuse=66\sin\theta = \frac{\text{opposite}}{\text{hypotenuse}} = \frac{\sqrt{6}}{6}, let the opposite side be 6\sqrt{6} and the hypotenuse be 66. Then, use the Pythagorean theorem to find the adjacent side:
Adjacent side=Hypotenuse2Opposite2.\text{Adjacent side} = \sqrt{\text{Hypotenuse}^2 - \text{Opposite}^2}.
Adjacent side=62(6)2=366=30.\text{Adjacent side} = \sqrt{6^2 - (\sqrt{6})^2} = \sqrt{36 - 6} = \sqrt{30}.
Thus, the adjacent side is 30\sqrt{30}.


Step 3: Compute Remaining Trigonometric Functions

Part 1: Secant (secθ\sec\theta)

secθ=HypotenuseAdjacent=630.\sec\theta = \frac{\text{Hypotenuse}}{\text{Adjacent}} = \frac{6}{\sqrt{30}}. Rationalize the denominator: secθ=63030=305.\sec\theta = \frac{6\sqrt{30}}{30} = \frac{\sqrt{30}}{5}.


Part 2: Cotangent (cotθ\cot\theta)

cotθ=AdjacentOpposite=306.\cot\theta = \frac{\text{Adjacent}}{\text{Opposite}} = \frac{\sqrt{30}}{\sqrt{6}}. Simplify the radicals: cotθ=306=5.\cot\theta = \sqrt{\frac{30}{6}} = \sqrt{5}.


Part 3: Sine (sinθ\sin\theta)

Already computed: sinθ=66.\sin\theta = \frac{\sqrt{6}}{6}.


Part 4: Cosine (cosθ\cos\theta)

cosθ=AdjacentHypotenuse=306.\cos\theta = \frac{\text{Adjacent}}{\text{Hypotenuse}} = \frac{\sqrt{30}}{6}.


Part 5: Tangent (tanθ\tan\theta)

tanθ=OppositeAdjacent=630.\tan\theta = \frac{\text{Opposite}}{\text{Adjacent}} = \frac{\sqrt{6}}{\sqrt{30}}. Simplify the radicals: tanθ=630=15=15.\tan\theta = \sqrt{\frac{6}{30}} = \sqrt{\frac{1}{5}} = \frac{1}{\sqrt{5}}. Rationalize the denominator: tanθ=55.\tan\theta = \frac{\sqrt{5}}{5}.


Final Answers

  1. secθ=305\sec\theta = \frac{\sqrt{30}}{5},
  2. cotθ=5\cot\theta = \sqrt{5},
  3. sinθ=66\sin\theta = \frac{\sqrt{6}}{6},
  4. cosθ=306\cos\theta = \frac{\sqrt{30}}{6},
  5. tanθ=55\tan\theta = \frac{\sqrt{5}}{5}.

Would you like me to clarify any step further? 😊

Here are 5 related questions to consider:

  1. What is the reciprocal of each trigonometric function?
  2. How does cscθ=6\csc\theta = \sqrt{6} relate to the unit circle?
  3. How do these values change if θ\theta is obtuse instead of acute?
  4. What are the exact values of these functions if cscθ=2\csc\theta = 2?
  5. Can we simplify tanθ\tan\theta further in terms of sine and cosine?
