I have tried so many times to figure out how to verify this identity! I need all the help I can get! Please help! I have tried so much! If you can tell me the steps to verify it, that would be SO HELPFUL!
SecB * cscB - 2(cosB * cscB) + cotB = tanB

Start by rewriting everything in terms of sines and cosines:
Now let's get a common denominator for the left side:
Now remember that, and substitute that into the numerator on the left side:
Finally, just cancel out the extra sine terms in the numerator and denominator:
There you have it! Did that all make sense?
