赤線部分についてです。私は｢any species｣を｢いかなる種｣と訳したのですが、日本語訳や解説を見るに、"any species"は"a species"という意味を表してるそうです。今までanyにひとつの物を限定するイメージを持っておらず、調べてもあまり理解できなか... Read More

When we call something a fruit, we necessarily distinguish it from vegetables, meat, dairy, and so on. 初期の人 組織した。彼らの精神と 基本的な私たちがまた 有効的に ② (1) Early humans organized their minds and thoughts around basic distinctions/that we still make and find useful. One of the earliest distinctions made was between now/and not-now; / these things are happening in the moment these other things happened in the past and are now in my memory. No other species makes this self-conscious distinction among past, present, and future. Of course many species respond to time by building nests, flying south, hibernating", 10 mating but these are preprogrammed, instinctive behaviors and these actions are not the 物体の永抂 result of conscious decision, meditation, or planning. 13 Simultaneous with an understanding of now versus before is one of (2) object permanence: Something may not be in my immediate view, but that does not mean it has ceased to exist.

In as other words those early cave-dwelling Picassos, through the very act of painting, were making a distinction about time and place and objects, an advanced cognitive operation we now call mental representation* And what they were demonstrating was an articulated sense of time: There was a deer out there (not here on the cave wall of course). He is not there now, but he was there before. 25 Now and before are different; here (the cave wall) is merely representing there (the meadow in front of the cave). This prehistoric step in the organization of our minds mattered a great deal. 5 In making such distinctions, (4) we are implicitly forming categories, something that is often す overlooked The formation of categories in humans is guided by a cognitive principle of wanting 多くの何報をできる! 325 h to encode as much information as possible with the least possible effort.

複素数平面の問題です。青線より下がよくわからないので解説お願いします。

例題 17 複素数平面上でO(0),A(1+i) とする。点z を直線 OA に関して対 称移動した点をwとするとき, wをz を用いて表せ。 指針 1+iの偏角を0とする。 点z を次の順で移動すればよい。 ① 原点を中心として-0だけ回転 (直線 OA が実軸に重なる) ② 実軸に関して対称移動 (共役な複素数をとる) ③原点を中心として0だけ回転(直線 OAがもとの位置に戻る) 「解答 1+iの偏角を 0 (0≦0 <2π) とすると 0 = π π 4 Q=COS sisin とすると,点zを原点を中心として 4 y 兀 - だけ回転した点を表す複素数は 4 2 w a 点を実軸に関して対称移動した点を表す複素数は O 1 x ( Z a 点wは,点(2)を原点を中心としてだけ回転した点であるから 答 w=α(4)=ºz=(cos(4-(-4))+sin(4-(-4)]== a a π 2= COS (一般) π
