Question

Among the statements :
I: If the given determinants are equal, then \( \cos^2\alpha + \cos^2\beta + \cos^2\gamma = \frac{3}{2} \), and
II: If the polynomial determinant equals \( px + q \), then \( p^2 = 196q^2 \), identify the truth value.

• A. both are true
• B. only I is true
• C. both are false
• D. only II is true

Hint:

To find \( q \) in a determinant equal to \( px+q \), simply substitute \( x=0 \) into the original determinant.

Answer 1

The Correct Option is D
