it was tan 1.5 fright? yeah i got a +ve answer and a -ve one

[Hamzeh S]

how was it 1 answer ? you also must subtract the angle-180

so 2 answers, the range was -180<x<180
tan we subtract 180 and add 180 unlike sin and cos which we add and subtract 360...

tan ? oh u mean the other question u got me worried for a sec hahahaha cause i did many silly mistakes
