# Evaluate the following definite integral:$\displaystyle\int_{4}^{12}x\ dx$

##### SOLUTION
$\displaystyle\int_{4}^{12}x\ dx$

$\implies\left.\dfrac {x^2}2\right|_4^{12}$

$\implies\dfrac {12^2}2 -\dfrac {4^2}2$

$\implies\dfrac {144}2-\dfrac {16}2$

$\implies72-8=64$

Q4 Subjective Medium
Evaluate:
$\displaystyle\int\dfrac{1}{(4x+5)^2+1}dx$

Given that for each $\displaystyle a \in (0, 1), \lim_{h \rightarrow 0^+} \int_h^{1-h} t^{-a} (1 -t)^{a-1}dt$ exists. Let this limit be $g(a)$
In addition, it is given that the function $g(a)$ is differentiable on $(0, 1)$
