the value of sqrt(1-sin^2 11 0^(@))*sec11 0^(@)

the value of sqrt(1-sin^2 11 0^(@))*sec11 0^(@)

If sec A-tan A=(1)/(2) and 0

If theta in the interval (0,pi/2) satisfying the equation cos2theta*sec^(4)theta+sec^(2)theta=0 , then sin^(2)theta =

lim_ (x rarr0) sin ^ (2) ((pi) / (2-px)) ^ (sec ^ (2) (((pi) / (2-4 pi))))

Evaluate : [{:(,4 sin 30^@ 2 cos 60^@), (,sin 90^@ 2 cos 0^@):}] [{:(,4,5),(,5,4):}]
