`M=[{:(sin^(4)theta,-1-sin^(2)theta),(1+cos^(2)theta,cos^(4)theta):}]=alphaI+betaM^(-1)`
Where `alpha=alpha(theta)` and `beta=beta(theta)` ar real numbers and I is an identity matric of `2xx2`
if `alpha^(**)=` min of set `{alpha(theta):thetain[0.2pi)}`
and `beta^(**)=` min of set `{beta(theta):thetain[0.2pi)}`
Then value of `alpha^(**)+beta^(**)` is
