If `cos A=7/25` and `3pi/2ltAlt2pi` ,then `cot (A/2)=`

If cos A=(7)/(25) and (3 pi)/2ltAlt2pi then cot((A)/(2))

If cos x=(-sqrt3)/2 and pi

If cosA=-24/25 and cos B=3/5 where pi < A < (3pi)/2 and (3pi)/2 < B < 2pi then find cos(A+B)

If (3pi)/(2)ltAlt2pi and sinA=-7//25 , then

cos ((3pi)/(2)+theta) cos (2pi+theta) xx [ cot ((3pi)/(2) -theta) + cot (2pi + theta) ] = ?

(sin (pi + x) cos ((pi) / (2) + x) tan ((3 pi) / (2) -x) cot (2 pi-x)) / (sin (2 pi-x) cos (2 pi + x) csc (-x) sin ((3 pi) / (2) -x)) = 1

sin ((pi) / (2) + theta) * cos ((3 pi) / (2) + theta) * tan ((5 pi) / (2) + theta) * cot ((7 pi) / (2) ) + theta)

If sin4A-cos2A=cos4A-sin2A ("where",0ltAlt(pi)/(4)) , then the value of tan 4A is
