Strong neutron generator (abbreviation for Intense Neutron Generator)

Both numerator and denominator are multiplied by 2sin(π/ 1 1):

Original formula = [2cos (π/11) sinπ/1-2cos2π/1sinπ/1+2cos (3π/.

The formula line is too long to edit. Let me introduce you to the method. Since you can ask this question, I'm sure you can finish it.

S 1:

Both the numerator and denominator are multiplied by "2sin(π/ 1 1)".

S2

Use: 2cosαsinβ=sin(α+β)-sin(α-β) to deform every term in the molecule,

S3

The simplified molecule is sin(π/ 1 1) and the denominator is 1/2.

Note: sin (5 π/11) = sin (6 π/1/).

Do it. Ask questions.
