Answer:

  • First, you want to divide the numerator and denominator by the cosine(x), and afterwards, it looks like this...

[tex]\frac{tan~x+1}{tan~x-1}[/tex]

  • Include 45 as one of the parameters and correlate with tan.

[tex]\frac{tan~x+tan~45}{tan~x-tan~45}[/tex]

  • Next, you want to multiply the numerator and denominator by the conjugate of the denominator, in this case, tan x + tan 45.
  • Lastly, simplify, and you have the answer as tan(45 + x)
