Minimum value of `24 cos^(2) x+ 16 sec^(2) x ` is

Statement I : Minimum value of (3 sn theta -4 cos theta ) ( 3 cos theta + 4 sin theta ) is -(25)/(2) Statement II : Minimum value of 9 tan^(2) x+ 16 cot^(2) x is 24 Which of the above statement is correct ?

The minimum value of 2 cos x - 3 cos^(2) x +5 is

the ratio of maximum and minimum value of 2-cos x+sin^(2)x is:

The minimum value of 3 sin^2x + 4 cos^(2) x is

The minimum value of 1-8sin^(2) x cos^(2) x is

A minimum value of sin x cos2x is -

the least value of cos ^2 x + sec ^2 x is

The least value of cos^(2)x+sec^(2)x is :

Minimum value of 27^(cos 2x) 81^( sin 2x) is

The minimum value of 2cos x-3cos^(2)x+5 is
