" If "x" cot "(90^(@)+1)+tan(90^(@)+1)sin A+csc(90^(@)+A)=(0)/(sqrt(3)(30))

Find the value of x. xcot(90^(@)+theta)+tan(90^(@)+theta)sintheta+cosec(90^(@)+theta)=0

Show that : sin A cos A - (sin A cos(90^(@) - A) cos A)/ (sec (90^(@) - A)) - (cos A sin (90^(@) - A) sin A)/ (cosec (90^(@) - A)) = 0

Find the value of x: i) xcot(90^(@)+theta)+tan(90^(@)+theta)sintheta+"cosec"(90^(@)+theta)=0 ii) "cosec"(90^(@)+theta)+x costhetacot(90^(@)+theta)=sin(90^(@)+theta)

Prove that : (1)/ (1 + cos (90^(@) - A)) + (1)/ (1 - cos (90^(@) - A)) = 2 cosec^(2) (90^(@) - A)

The value of (cos (90^(@) + A) sec ( 360^(@) - A) tan ( 180^(@) - A))/( sec (A - 720^(@)) sin ( 54 0 ^(@) + A) cot (A - 90^(@))) is

Find the value of x: "cosec"(90^(@)+theta)+x costhetacot(90^(@)+theta)=sin(90^(@)+theta)

If cosec (90^@+A) + x cot A cot (90^@+A) = sin (90^@+A) , find x.

Check and discuss the above relations [sin (90^@ - x) = (AB) /(AC) = cos x cos (90^@ - x) = (BC)/(AC) = sin x tan (90^@ - x) = (AB)/(BC) = cot x cot(90^@ - x) = (BC)/(AB) = tan x , cosec(90^@ - x) = (AC)/(AB) = sec x , sec(90^@ - x) = (AC)/(BC) = cosec x] , in the case of angle between 0^@ and 90^@ , whether they hold for these angles or not ?So, sin(90^@ - A) = cosA
