` cot A +tan ( 180^(@) +A )+ tan ( 90^(@) +A) +tan ( 360^(@) -A)=0`

Simplify : ("sec"(270^@ - A) "sec"(90^@ - A) - tan (270^@ -A) tan (90^@ + A))/(cot A + tan (180^@ + A) + tan (90^@ + A) + tan (360^@ - A) + cos 180^@)

(cos(180^(@)-A)*cot(90^@+A)*cos(-A))/(tan(180^(@)+A) tan(270^(@) +A)* sin(360^(@)-A))=

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

tan A+cot(180^(@)+A)+cot(90^(@)+A)+cot(360^(@)-A)=

tanA+tan(180^(@)+A)+cot(90^(@)+A)+cot(360^(@)-A)=?

If tan theta = -(5)/(12) and theta is not in the fourth quadrant then ( tan (90^(@)+ theta ) - sin(180^(@) - theta ))/( sin (270^(@)- theta ) + " cosec " (360^(@) - theta ))=

Assertion (A) : tan 70^(@) - tan 20^(@) = 2 cot 40^(@) Reason (R ) : If A + B = 90^(@) then tan A. tan B = 1
