The correct Answer is:
To solve the equation \( \csc\left(\frac{\pi}{4}\right) - \sin\left(\frac{\pi}{3}\right) = x \), we will follow these steps: ### Step 1: Calculate \( \csc\left(\frac{\pi}{4}\right) \) The cosecant function is the reciprocal of the sine function. Therefore, we need to find \( \sin\left(\frac{\pi}{4}\right) \). \[ \sin\left(\frac{\pi}{4}\right) = \frac{\sqrt{2}}{2} \] Thus, \[ \csc\left(\frac{\pi}{4}\right) = \frac{1}{\sin\left(\frac{\pi}{4}\right)} = \frac{1}{\frac{\sqrt{2}}{2}} = \frac{2}{\sqrt{2}} = \sqrt{2} \] ### Step 2: Calculate \( \sin\left(\frac{\pi}{3}\right) \) Now, we calculate \( \sin\left(\frac{\pi}{3}\right) \). \[ \sin\left(\frac{\pi}{3}\right) = \frac{\sqrt{3}}{2} \] ### Step 3: Substitute the values into the equation Now we substitute the values we found into the original equation. \[ x = \csc\left(\frac{\pi}{4}\right) - \sin\left(\frac{\pi}{3}\right) \] Substituting the values: \[ x = \sqrt{2} - \frac{\sqrt{3}}{2} \] ### Step 4: Find a common denominator To combine the terms, we can express \( \sqrt{2} \) with a common denominator of 2: \[ \sqrt{2} = \frac{2\sqrt{2}}{2} \] Thus, \[ x = \frac{2\sqrt{2}}{2} - \frac{\sqrt{3}}{2} \] ### Step 5: Combine the fractions Now we can combine the fractions: \[ x = \frac{2\sqrt{2} - \sqrt{3}}{2} \] ### Conclusion So, the value of \( x \) is: \[ x = \frac{2\sqrt{2} - \sqrt{3}}{2} \]
