Integrate and differentiate trigonometry

$\dfrac{d}{dx} \pi = 0$ ( $\pi$ is constant)
$\dfrac{d}{dx} x = 1$ .

So, the question reduces to $\int_{0}^{1} \sin(x)\cos(x)\tan(x)\csc(x)\sec(x)\cot(x) \ dx$ . The trigonometric functions cancel out with their respective reciprocal functions to yield $1$ . So, the question reduces to $\int_{0}^{1} 1 \ dx = \color{#3D99F6}{\boxed{1}}$ .
