Question

find the maximum value of determinant ( 1 1 1, 1 1+sin theta 1, 1 1 1+cos theta

Answer 1

(111,11+sin theta1,111+cos theta)
solve this determinant we find ,
sin theta. cos theta=1/2(2sin theta.cos theta)=1/2 .sin2theta
but we know sine maximum value is 1
hence determinant maximum value=1/2 (1)=1/2
