`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^@)

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

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

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

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

tanA+cot(180^@+A)+cot(90^@+A)+cot(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

((1180 + A) * tan (270 + A) * sin (360-A)) / (cos (180-A) * cot (90 + A) * cos (-A) =)
