下線部Dと答え.ウはなぜ同じ用法なんでしょうか 教えてください🙏

closer to reality. Researchers have investigated the use of electricity to stimulate vision for nearly half a century. In the 1960's, a *physiologist implanted 80 electrodes on the surface of a blind person's *visual cortex, a region at the back of the brain. Wireless stimulation of the electrodes made the patient see spots of light known as *phosphenes. This is the first stop for visual signals coming from the eye. (D) By the 1980's, a crop of *ophthalmologists began considering a narrower and seemingly easier-to-solve problem: making *prostheses for the eye. They suggested that degrade *photoreceptor cells called *rods and cones, still leave large portions of the retina intact even after a patient has become totally blind. The way to stimulate the remaining functional cells was proved *feasible in the mid-1990's. A device consisting of a tiny video camera perched on the bridge of a pair of glasses, a belt-worn video processing unit, and an electronic box, was developed recently. The electronic box issues signals to an implant behind the patient's ear that has wires running to a grid of 16 electrodes affixed to the output layer of the retina. The video processor wirelessly transmits a simplified picture of what the camera images to the box, and then the retinal implant stimulates cells in a pattern roughly reflecting that information.

例題 33] Pを放物線y=-x上の点とし, Qを点 (-5, 1) とする。 2点P. Qを通る直線が,点Pにおける接線と直交しているときの点Pの座標を求め [01 崇城大] よ。 指針 法線の方程式 2直線が直交 を利用する。 > 傾きの積=-1 解答 Pt,t) とおく。 y'=-2x であるから,点Pにおける接線lの傾きは-2t t=0 のとき, lはx軸と一致する。 このとき,直線PQはx軸と直交しない。 -(x-t)-t² 2 x-2t=-1 よって t≠0 ゆえに、直線 PQ の方程式は y= 2t この直線が点Qを通るから 1= 2t 1=24+ (-5-t)-t² ゆえに 2t3+3t+5=0 よって (t+1)(2t2-2t+5)=0 2 9 2t2-2t+5=2t + >0 ゆえにt=-1 2 2 したがって,求める点Pの座標は(-1, -1)
