Pray, dost thou not find it a marvel, a wondrous creation, this Quadcopter with its video camera, directed downwards towards the bountiful surface of our fair Earth? Ah, verily, it doth rise aloft, ascending vertically at a gentle pace, with a speed akin to the square root of three meters per second. A spectacle, indeed, to witness such a contrivance navigate the realms of our mortal realm.

But lo, I am beseeched to inquire upon another matter of no small import. A question of the utmost gravity doth arise: what shall be the rate at which the area of vision doth change at the very inception of this endeavor? Mayhaps thou art acquainted with the values I have been given: a radius of initial observation, R0, with a magnitude of ten centimeters; and an angle of vision, 2α, measuring one hundred and twenty degrees. Let it be known that the square root of three equals one point seven three.

To bestow thee with insight, I shall unravel this quandary using the intricacies of mathematical discernment. First, we must establish the rate at which the radius of observation, R, shall alter with the passage of time. However, such a calculation must be predicated upon the understanding that the angle of vision remains constant. By employing the properties of a right-angled triangle, one can surmise that the change in radius, dR, shall be equal to the product of twice the radius of observation, R0, and the rate of ascent, v.

Thus, we derive the equation: dR = 2R0v.

Once this foundation is laid, we can proceed towards ascertaining the alteration of visual area, dS, at the inception of our journey. Verily, this change in area is proportionate to the product of the increase in radius, dR, and the radius of observation, R.

Henceforth, we arrive at the equation: dS = dR * R.

But hark, fairest readers, patience dost lead us further still. In our quest for esteeming this transformation with utmost precision, a value for the rate at which the visual area alters must be found. This precious tidbit of knowledge shall provide the desired insight into the rate of change of visual perception.

Utilizing the established equations and the knowledge that the initial radius of observation, R0, measures ten centimeters, and that the angle of vision, 2α, equates to one hundred and twenty degrees, we discover that the change in visual area, dS, shall amount to three point four six.

This, then, is the answer to the question posed. The rate of change of visual area, in the initial moment, with due precision, shall be three point four six square meters per second. Thus, doth unfold the beauty of mathematical enlightenment, allowing us to comprehend the intricacies of this divine creation of Quadcopter and its heavenly vision.
