# Question #74e29

##### 1 Answer

#### Answer:

When in doubt, rewrite using sine and cosine. See below.

#### Explanation:

Factor out

# = (sin(theta)(sin(theta)-1/(cos(theta))))/(cos(theta)(cos(theta)-1/sin(theta)))#

For the remaining quotient, get a single fraction over another fraction. (No I'm not certain it will work, but I have to try something, so . . . )

# = tan(theta) (((sin(theta)cos(theta)-1)/(cos(theta))))/(((sin(theta)cos(theta)-1)/(sin(theta))))#

We now see that we have the same numerators, so when we invert the denominator and multiply, the
