Explanation
For step 2, we rewrite each expression in terms of sines and/or cosines. For instance, tan = sin/cos.
In step 3, we focus on the stuff in the numerator only. So we focus on sin/cos+cos/sin. In this step, we multiply top and bottom of the first fraction by sine. We multiply top and bottom of the second fraction by cos. These steps are done to get the LCD.
In step 4, we are able to add the fractions because both fractions have the same denominator.
In step 5, we use the pythagorean trig identity sin^2+cos^2 = 1.
In step 6, we use the idea that (A/B) divide by (C/D) = (A/B)*(D/C).
