Triangle angle -- sin1

Triangle angle -- sin1

1 represents 1 radian
sin1=sin57.3°=0.842

sin1

Sin1, sin2, where 1 and 2 belong to the radian system, just like sin π, the angle system is
sinπ=sin180º=0
sin1≈sin(180º/3.14)≈sin57.32º≈ 0.84

Find y = sin1 / 2x image, X ∈ [0,2 π]
It's SiNx / 2,

The period of y = sin (1 / 2x) t = 2 π / (1 / 2) = 4 π your drawing x ∈ [0,2 π] is a half period. Below I give a list of X ∈ [0,4 π] 1 period: & nbsp; X & nbsp; & nbsp; & nbsp; & nbsp; 0 & nbsp; & nbsp; & nbsp; & nbsp; π & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 2 π & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp
