The correct Answer is:
To solve the problem step by step, we start with the given equation: 1. **Given Equation**: \[ \sin^2 \alpha + \sin^2 \beta + \cos^2 \gamma = 3 \] 2. **Understanding the Range**: - We know that the range of \(\sin^2\) and \(\cos^2\) functions is from 0 to 1. - Therefore, for the sum to equal 3, each term must equal its maximum value of 1: \[ \sin^2 \alpha = 1, \quad \sin^2 \beta = 1, \quad \cos^2 \gamma = 1 \] 3. **Finding Values of Angles**: - From \(\sin^2 \alpha = 1\), we conclude: \[ \sin \alpha = 1 \implies \alpha = 90^\circ \] - From \(\sin^2 \beta = 1\), we conclude: \[ \sin \beta = 1 \implies \beta = 90^\circ \] - From \(\cos^2 \gamma = 1\), we conclude: \[ \cos \gamma = 1 \implies \gamma = 0^\circ \] 4. **Calculating the Sum of Angles**: - Now, we compute \(\alpha + \beta + \gamma\): \[ \alpha + \beta + \gamma = 90^\circ + 90^\circ + 0^\circ = 180^\circ \] 5. **Finding the Required Expression**: - We need to find: \[ \tan\left(\frac{\alpha + \beta + \gamma}{4}\right) + \cot\left(\frac{\alpha + \beta + \gamma}{4}\right) \] - Substituting the sum of angles: \[ \tan\left(\frac{180^\circ}{4}\right) + \cot\left(\frac{180^\circ}{4}\right) = \tan(45^\circ) + \cot(45^\circ) \] 6. **Calculating \(\tan(45^\circ)\) and \(\cot(45^\circ)\)**: - We know: \[ \tan(45^\circ) = 1 \quad \text{and} \quad \cot(45^\circ) = 1 \] - Therefore: \[ \tan(45^\circ) + \cot(45^\circ) = 1 + 1 = 2 \] 7. **Final Answer**: - The final result is: \[ \boxed{2} \]
