Prove that cos theta(sin theta +-sqrt(sin^(2) theta+ sin^(2) alpha)) always lies between +- sqrt(1+sin^(2) alpha) .

The minimum and maximum values of expression y=cos theta(sin theta+sqrt(sin^(2)theta+sin^(2)alpha))

Show that the expression cos theta(sin theta+sqrt(sin^(2)theta+sin^(2)alpha)) always lies between the values of +-sqrt(1+sin^(2)alpha)

If | cos theta{ sin theta + sqrt( sin^(2) theta + sin^(2) alpha)}|le k , then the value of k is

If abs(cos theta{sin theta+sqrt(sin^2theta+sin^2alpha)})lek , then the value of k

If abs(cos theta{sin theta+sqrt(sin^2theta+sin^2alpha)})lek , then the value of k

If abs(cos theta{sin theta+sqrt(sin^2theta+sin^2alpha)})lek , then the value of k

cos theta+sin theta=cos2 theta+sin2 theta

If cos theta+cos^(2)theta=1 then sin^(2)theta+2sin^(2)theta+sin^(2)theta=
