how to solve it? I do not have problem with only one function, but this is overwhelming.

Any tries?

@agile turtle 1-cosx is always positive except on x=kπ where its 0. so you can divide by 1-cosx and say x≠kπ for all k=0,1,2,3,... Now you have to find (where sinx-cosx is positive and cosx is negative) and where (sinx-cosx is negative and cosx positive ).
