Step 1: Differentiate both sides.
Derivative of \(\ln 2\) is 0 (constant).
Derivative of \(\ln x\) is \(\frac{1}{x}\).
Step 2: Final result.
\(\frac{d}{dx}[\ln(2x)] = \frac{1}{x}\).
The value of \( \lim_{x \to 0} [ \dfrac{x - \sin 2x}{x - \sin 5x} ] \) (rounded off to two decimal places) is \(\underline{\hspace{1cm}}\).
Calculate the integral:
\[ \int_{0}^{\pi/4} \sin\sqrt{x}\ dx = \underline{\hspace{1cm}} . \]
