Specify the solving method
Find the derivative of $\frac{2}{3}a$ using the definition. Apply the definition of the derivative: $\displaystyle f'(x)=\lim_{h\to0}\frac{f(x+h)-f(x)}{h}$. The function $f(x)$ is the function we want to differentiate, which is $\frac{2}{3}a$. Substituting $f(x+h)$ and $f(x)$ on the limit, we get
