Establish the identity.
- tan + sec 8-1
- tane- sec +1 =
tan + seco
- sec 0 + 1
Since this fraction is equivalent to 1, the product is unchanged.
- tan
Multiply the right side of the identity by the fraction –
( (-tan 8 - sec 0 +1)
- tan + sec = -tan 8 - sec 0+1
Multiply and combine like terms in the numerator.
- tan 8 - sec 8 + 7 (Do not factor)
The simplified numerator from the previous step is equivalent to - tan
+ sec 0 - 1 using what?
