trig help?!?!?
is tan/sec/cosec/sin/cos/cot(360+x) = trig ratio(x)
what would happen if we replace with 180 and 90 and also 270 ., please tell for each trig function..

tan/sec/cosec/sin/cos/cot(360+x) = tan/sec/cosec/sin/cos/cot(x)
There are different cases for each of 90, 180 and also 270.
tan/sec/cosec/sin/cos/cot(90+x) = cot/sec/-cosec/cos/-sin/tan(x).
tan/sec/cosec/sin/cos/cot(180+x) = tan/-sec/-cosec/-sin/-cos/cot(x).
tan/sec/cosec/sin/cos/cot(270+x) = -cot/sec/-cosec/-sin/cos/ -tan(- 90+x)
= tan/sec/cosec/sin/cos/cot(x),
since, 270+x = (360 -90)+x = - 90+x.
Also I wish to add here
tan/sec/cosec/sin/cos/cot(180 -x) = -tan/-sec/cosec/sin/-cos/-cot(x),
which is more important than all the above .
{I hope you possess enough human intelligence to keep/follow the order of the functions in the same order you wrote them.}
