Answer 1

Answer:

−8.660254

−4330127/500000

-8 330127/500000

Step-by-step explanation:

tan(3.141593/3)+2(tan((2)(3.141593)/3))+4(tan((4)(3.141593)/3))+8(tan((8)(3.141593)/3))

=tan(1.047198)+2(tan((2)(3.141593)/3))+4(tan((4)(3.141593)/3))+8(tan((8)(3.141593)/3))

=1.732051+2(tan((2)(3.141593)/3))+4(tan((4)(3.141593)/3))+8(tan((8)(3.141593)/3))

=1.732051+2(tan(6.283185/3))+4(tan((4)(3.141593)/3))+8(tan((8)(3.141593)/3))

=1.732051+2(tan(2.094395))+4(tan((4)(3.141593)/3))+8(tan((8)(3.141593)/3))

=1.732051+(2)(−1.732051)+4(tan((4)(3.141593)/3))+8(tan((8)(3.141593)/3))

=1.732051+−3.464102+4(tan((4)(3.141593)/3))+8(tan((8)(3.141593)/3))

=−1.732051+4(tan((4)(3.141593)/3))+8(tan((8)(3.141593)/3))

=−1.732051+4(tan(12.566371/3))+8(tan((8)(3.141593)/3))

=−1.732051+4(tan(4.18879))+8(tan((8)(3.141593)/3))

=−1.732051+(4)(1.732051)+8(tan((8)(3.141593)/3))

=−1.732051+6.928203+8(tan((8)(3.141593)/3))

=5.196152+8(tan((8)(3.141593)/3))

=5.196152+8(tan(25.132741/3))

=5.196152+8(tan(8.37758))

=5.196152+(8)(−1.732051)

=5.196152+−13.856406

=−8.660254
