what have you tried here? you must have gotten farther than I showed you. if nothing else you could follow your nose, add the fractions and attempt to simplify. show me where you got stuck

for

Now check all those solutions to make sure they work

Quote:

b)

............i cross-multiplied

.................i factored out the common tan(x)

for

Check those solutions as well.
