tan(π/4 + 6)
(tan π/4 + tan 6)/ (1 - tam π/4 . tan 6)
(1 + tan6)/(1 - tan6)
(1 + sin6/cos6) / (1 - sin6/cos6)
(cos6 + sin6)/cos6 ÷ (cos6 - sin6)/cos6
(cos6 + sin6)/(cos6 - sin6)
Rationalizing the denominator
(cos6 + sin6)/(cos6 - sin6) × (cos6 + sin6)/(cos6 + sin6)
(cos6 + sin6)² / (cos²6 - sin²6)
(cos²6 + 2cos6.sin6 + sin²6)/ cos12
(1 + sin12)/cos12
1/cos12 + sin12/cos12
sec12 + tan12
1.18 + (-0.635) = 0.545 is Answer
Therefore
tan(π/4 + 6) = 0.545 is Answer
