If `A = [(1,sintheta,1),(-sintheta,1,sintheta),(-1,-sintheta,1)]`, then for all
`thetain ((3pi)/(4),(5pi)/(4))`, det. (A) lies in the interval

If A= [{:(1, "sin"theta,1), (-"sin"theta, 1, "sin" theta),(-1, -"sin"theta, 1):}], " then for all "theta in ((3pi)/(4), (5pi)/(4)) det (A) lies in the interval

If Delta=|{:(1,sintheta,1),(-sintheta,1,sintheta),(-1,-sintheta,1):}|"prove that" 2lt=Deltalt=4.

sqrt((1+sintheta)/(1-sintheta)) = __.

If A=[(costheta,-sintheta),(sintheta,costheta)] " then " A^(-1) =?

((1-sintheta+costheta)^(2))/((1+costheta)(1-sintheta))=?

If cos theta-4sintheta=1, the sintheta+4costheta=

If A=[[costheta, sintheta], [-sintheta, costheta]] , then |A^(-1)|=

Let A=[(1,sintheta, 1),(-sintheta, 1, sintheta),(-1, -sintheta, 1)], where 0lethetalt2pi then (A) |A|=0 (B) |A|epsilon[2,4] (C) |A|epsilon)(0,oo) (D) |A|epsilon(2,oo)

(1-costheta)/(sintheta)+(sintheta)/(1-costheta) =___________.
