The most important thing about inverse trigonometry is remembering domain and range of the functions.

Secondly you should remember graphs of all of them to solve some particular very fast.

$\\cosec^{-1}x\,domain=(-\infty,\infty)\,range=[-\Pi/2,0)or(0,\Pi/2] \\cos^{-1}x\,domain=[-1,1]\,range=[0,\Pi] \\cot^{-1}x\,domain=(-\infty,\infty)\,range=[-\Pi/2,0)or(0,\Pi/2] \\sec^{-1}x\,domain=(-\infty,\infty)\,range=[0,\Pi/2)or(\Pi/2,\Pi] \\sin^{-1}x\,domain=[-1,1]\,range=[-\Pi/2,\Pi/2] \\tan^{-1}x\,domain=(-\infty,\infty)\,range=(-\Pi/2,\Pi/2]$
