Solution

To find the exact value of sinθ\sin \theta given that cscθ=10\csc \theta = 10, we start by using the reciprocal identity that relates cosecant and sine:

cscθ=1sinθ\csc \theta = \frac{1}{\sin \theta}

Since cscθ=10\csc \theta = 10, we have:

10=1sinθ10 = \frac{1}{\sin \theta}

To solve for sinθ\sin \theta, take the reciprocal of both sides:

sinθ=110\sin \theta = \frac{1}{10}

So, the exact value of sinθ\sin \theta is:

sinθ=110\sin \theta = \frac{1}{10}

Would you like to proceed with finding the remaining trigonometric functions or need further explanation on any step?


Here are some related questions to deepen your understanding:

  1. How do you find cosθ\cos \theta given sinθ\sin \theta using the Pythagorean identity?
  2. What is the relationship between secθ\sec \theta and cosθ\cos \theta?
  3. How do we find tanθ\tan \theta using the values of sinθ\sin \theta and cosθ\cos \theta?
  4. Can you explain why the reciprocal identities are helpful in trigonometry?
  5. How would you find cotθ\cot \theta once tanθ\tan \theta is known?

Tip: Remember, knowing just one trigonometric function's value often allows you to determine all six, especially with identities and the Pythagorean theorem.
