Hi! This is a very generic question compared to the others, but I'm doing Prelims next term, and i was wondering for all exams (HSC Trials,Prelims) involving 3D trigonometry, are diagrams always given?? I have done a lot of practice questions involving them but there are certain ones without diagrams and require you to draw them, and i really struggle at drawing the correct diagram whilst being crammed with tons of info on bearings, numbers and letters.
Hey there humble mango!! Aha Rui is right, although I have seen
one question with it in a weird Trial, I remember thinking "wtf" when I saw it back in 2014
but you are pretty safe I reckon!
Some tips on the diagram in case it does pop up; underline all the angles and data you are given and make sure that all of it goes in, don't miss anything, that's a good start. Besides that, draw the diagram in pieces, adding information piece at a time and crossing off as you go. Draw in pencil and fix mistakes. Or, alternatively, scribble a draft to make sure everything fits together nicely before the final version. Finally,
take your time! The diagram is crucial for understanding and interpreting the question, best to spend some time to get it right
