Grade 9Trigonometry

while solving ITF questions, when the domain is given out of the general domain and you’ve to balance it by adding pi or pi/2 or whatever value. In general questions though I am able to do it but in somewhat other questions out of the formatt when you finally arrive at the result, it gets really confusing to balance it. SO IF YOU CAN EXPLAIM ME THE BASIC TRICK TO DO IT OR PROVIDE SOME REFERENCE MATERIAL OR VIDEO ON UYUBE OR YOUR EXPLANATION IT WOULD BE OF GREAT HELP.
