Tan(45-alpha)=(1-tan alpha)/(1+tan alpha)
this formula is helpful when we need to expand  Tan(45-alpha) in order to solve a problem or prove an identity.

Dear student
Tan(45-alpha)=(tan 45-tan alpha)/(1+(tan alpha)(tan45))
                       =(1-tan alpha)/(1+tan alpha)                                  [as tan45=1 ]
This formula is helpful to solve many sums in trigonometry related to compound angles and also to prove identities
 
I hope this answer helps you.
