Straight to the question:
Given that 0 <= t < 2*PI
How can one prove analytically that
atan(1/tan(t/2)) = 0.5(pi - t)
There are some posts that make me wonder if this group should be renamed
"sci.math.homework" or "sci.math.homework.duesoon".
Any /meaningful/ homework assignment, say in trigonometry, should contain at
least 30-50 such problems.
Asking about ONE such problem and seeing the solution won't alter the
assignment or the student's understanding of the assignment's matter very
much, if the student has 30 more to do. As such it is harmless.
It's much more harmful when seniors post single hard exercises expecting a
solution here.
