" le "5" Express "tan^(1)(cos x)/(1-sin x),-(pi)/(2)

Express tan^(-1) ((cos x )/( 1- sin x) ) , ( -3 pi)/(2) lt x lt (pi)/(2) in the simplest form

Solve : tan^(-1)((cos x)/(1+sin x)) , -(pi)/(2) lt x lt (pi)/(2)

Solve the equation sqrt(|sin^(-1)| cos x|| + |cos^(-1)| sin x||) = sin^(-1)|cos x | -cos^(-1)| sin x|, (-pi)/(2) le x le (pi)/(2)

The value of the expression sin^(-1)((sin(22 pi))/(7))+cos^(-1)((cos(5 pi))/(3))+tan^(-1)((tan(5 pi))/(7))+sin^(-1)(cos2) is (a) (17 pi)/(42)-2( b) -2( c) (-pi)/(21)-2( d) noneofthese

The expression (tan(x-pi/2)cos((3pi)/2+x)-sin^3((7pi)/2-x))/(cos(x-pi/2)tan((3pi)/2+x) is equal to

If f (x) = tan ^(-1)sqrt((1 + sin x )/(1 - sin x)), 0 le x le (pi)/(2) then f' ((pi)/(6)) =?

If f (x) = tan ^(-1)sqrt((1 + sin x )/(1 - sin x)), 0 le x le (pi)/(2) then f' ((pi)/(6)) =?
