Chapter 4: Q. 47 (page 400)

Use the Second Fundamental Theorem of Calculus, if needed, to calculate each of the derivatives given below.
$\frac{d}{d x} {鈭�}_{x}^{x + 2} 鈥� \sin 鈦� (t^{2}) d t$

Short Answer

Expert verified

Ans: $\frac{d}{d x} {鈭�}_{x}^{x + 2} 鈥� \sin 鈦� (t^{2}) d t = \sin 鈦� ((x + 2)^{2}) 鈭� \sin 鈦� (x^{2})$

Step by step solution

Step 1. Given information.

given expression,

$\frac{d}{d x} {鈭�}_{x}^{x + 2} 鈥� \sin 鈦� (t^{2}) d t$

Step 2. The objective is to calculate the derivative.

The derivative can be written as,

$\begin{aligned} \frac{d}{d x} ({鈭�}_{x}^{0} 鈥� \sin 鈦� (t^{2}) d t + {鈭�}_{0}^{x + 2} 鈥� \sin 鈦� (t^{2})) \\ = \frac{d}{d x} (鈭� {鈭�}_{0}^{x} 鈥� \sin 鈦� (t^{2}) d t + {鈭�}_{0}^{x + 2} 鈥� \sin 鈦� (t^{2})) \end{aligned}$

Now, if $f$ is continuous on role="math" localid="1648717234298" $[a, b]$ then for all role="math" localid="1648717239014" $x 鈭� [a, b]$ ,

$\frac{d}{d x} {鈭�}_{a}^{u (x)} 鈥� f (t) d t = f (u (x)) u^{鈥�} (x)$

Step 3. The derivate expression can be written as,

$\begin{aligned} \frac{d}{d x} (鈭� {鈭�}_{0}^{x} 鈥� \sin 鈦� (t^{2}) d t + {鈭�}_{0}^{x + 2} 鈥� \sin 鈦� (t^{2})) \\ = 鈭� \sin 鈦� (x^{2}) + \sin 鈦� ((x + 2)^{2}) \\ = \sin 鈦� ((x + 2)^{2}) 鈭� \sin 鈦� (x^{2}) \end{aligned}$

Therefore, the answer is $\sin 鈦� ((x + 2)^{2}) 鈭� \sin 鈦� (x^{2})$
