What did you get for part d) ?
Look closely between the relationship in the equations in parts d) and e)
There is no difference given
Can anyone help with this question?
I have done all of the parts except the last bit, kinda went a bit over my head there :S
There is also this question that I have gotten really stumped with, I have to try and prove the identitiy, we have only covered the first trig identity so far but we have been set this question, so I am not quite sure what I can do :S
