tan(180+A)= tan A
tan(90 +A) = - cot A
tan (360 -A) =- tan A
lhs = cot A +tan (180+A) + tan (90 +A) +tan (360 -A)
= cotA +tan A -cot A -tan A
= 0
option A is correct
tan(90 +A) = - cot A
tan (360 -A) =- tan A
lhs = cot A +tan (180+A) + tan (90 +A) +tan (360 -A)
= cotA +tan A -cot A -tan A
= 0
option A is correct
thanks alot
