Best answer:
x = sqrt(2) + sqrt(17)
x^2 = 2 + 2 * sqrt(2) * sqrt(17) + 17
x^2 = 19 + 2 * sqrt(34)
x^2 - 19 = 2 * sqrt(34)
x^4 - 38x^2 + 361 = 4 * 34
x^4 - 38x^2 + 361 = 136
x^4 - 38 * x^2 + 225 = 0
Now, if divisors of 225 can provide a solution for this polynomial, then sqrt(2) + sqrt(17) is rational. If not, then it...

Best answer:
tan(4t) =>
2 * tan(2t) / (1 - tan(2t)^2)
tan(2t) =>
2 * tan(t) / (1 - tan(2t)^2) =>
2 * (-4/3) / (1 - (-4/3)^2) =>
(-8/3) / (1 - 16/9) =>
(-8/3) / (-7/9) =>
(-8/3) * (-9/7) =>
72/21 =>
24/7
2 * tan(2t) / (1 - tan(2t)^2) =>
2 * (24/7) / (1 - (24/7)^2) =>
(48/7) / (1 - 576/49)...
