## How do you find the horizontal shift of sin?
the horizontal shift is obtained by determining the change being made to the x-value. The horizontal shift is C. The easiest way to determine horizontal shift is to determine by how many units the “starting point” (0,0) of a standard sine curve, y = sin(x), has moved to ... | HuggingFaceTB/finemath | |

# A conjectural expression for N2(n)
The definition of a « typical » primality radius $r$ of $n$ leads to the following assumption:
the following ratio: $\dfrac{N_{2}(n)}{N_{1}(n)}$
is asymptotically equal to the ratio: $\dfrac{n-\sqrt{2n-3}}{P_{ord_{c}(n)}-\sqrt{2n-3}}$
