" 5.if "Delta=|[1,3cos theta,1],[sin theta,1,3cos theta],[1,sin theta,1]|" ,then the value of "(Delta_(1),x_(1))" is equal to "

If Delta=|(1,3cos theta,1),(sin theta,1,3cos theta),(1,sin theta,1)|, then the 1/1000 [|maximum value of Delta- minimum value of Delta|^3 ] is equal to.

If Delta=det[[1,3cos theta,1sin theta,1,3cos theta1,sin theta,1]], then the 1000, l|maximum value of Delta- minimum value of Delta|^(3)] is equal to.

If Delta=det[[1,3cos theta,1sin theta,1,3cos theta1,sin theta,1]] then the (1)/(1000),[maximum value of Delta- minimum value of Delta|^(3)] is equal to

,x,sin theta,cos theta-sin theta,-x,1cos theta,1,x]|=8, write the value

(cos theta)/(1-sin theta)=(1+cos theta+sin theta)/(1+cos theta-sin theta)

(sin theta)/(1-cos theta)=(1+cos theta)/(sin theta)

(1+cos theta+sin theta)/(1+cos theta-sin theta)=(1+sin theta)/(cos theta)

cos theta/(1+sin theta)=(1-sin theta)/cos theta

Let A=[(1,3cos 2theta,1),(sin2theta, 1, 3 cos 2 theta),(1, sin 2 theta, 1)] the maximum value of |A| is equal to k, then (k-3)^(2) is equal to
