• ### Integral of cos(x)/(sin(x) + cos(x)) - LearnMathsFree

1,099 views 1 year ago
In this video, we look at a unique method of solving the integral of cos(x)/(sin(x) + cos(x)) over the interval [0, pi/4], without using any substitutions!

NOTE: Although I did say at the end of the video that there are all sorts of tricks and strategies you can use for integrals like these, this is definitely not true in general -- in fact, many of the integrals you find in research (including some integrals in my own research!) do not have nice, closed form solutions like this one.
