Hi,
I've been doing some additional maths papers and I've seen the use of the substitution u=tan(x/2) in order to calculate integrals. In the mark scheme it states that this particular substitution used to be fairly common, however is not on the modern A-level syllabus.
Would someone please mind advising me of suitable situations to use such a substitution? I am struggling to see when I should use it.
Thanks,
Oscar
