(1 - tan2x)/(1 + tan2x) = (1 - sin2x/cos2x)/(1 + sin2x/cos2x)
= (cos2x - sin2x)/(cos2x + sin2x)
= (cos2x - sin2x)/1 = (cos2x - sin2x) = cos(2x)
2 times the Square root of 3 + 4
Because there is no way to define the divisors, the equations cannot be evaluated.
No, it cannot be simplified.
4 factorial plus 4 factorial plus the square root of 4 divided by .4
