1. The problem states that $A = \frac{\sqrt{3}}{2} \cdot N$. We want to understand or simplify this expression. 2. This expression means that $A$ is equal to $N$ multiplied by $\frac{\sqrt{3}}{2}$. The fraction $\frac{\sqrt{3}}{2}$ is a constant approximately equal to 0.866. 3. If you know the value of $N$, you can find $A$ by multiplying $N$ by $\frac{\sqrt{3}}{2}$. For example, if $N=4$, then: $$A = \frac{\sqrt{3}}{2} \times 4 = 4 \times \frac{\sqrt{3}}{2}$$ 4. Simplify by multiplying numerator and denominator: $$A = \frac{4 \sqrt{3}}{2} = 2 \sqrt{3}$$ 5. So, $A$ depends linearly on $N$ with the factor $\frac{\sqrt{3}}{2}$. This is the complete explanation for the given expression.
