The teacher will be very surprised to see your correct solution 😉
sin(pi*(4*x + 12))
------------------ = 0.5
6
Divide both parts of the equation by 1/6
True
sum
0.125 - 0.140274963084795*I + 0.125 + 0.140274963084795*I
=
0.250000000000000
product
(0.125 - 0.140274963084795*I)*(0.125 + 0.140274963084795*I)
=
0.0353020652684406
0.0353020652684406
x1 = 0.125 - 0.140274963084795*I
x2 = 0.125 + 0.140274963084795*I
x2 = 0.125 + 0.140274963084795*i
x1 = 0.125 - 0.140274963084795*i
x2 = 0.125 + 0.140274963084795*i
x2 = 0.125 + 0.140274963084795*i
