These days, however, new discoveries about babies show us that they have much greater abilities than most people think. 1B 2 Recent research findings in brain science and cognitive psychology make it clear that babies are not necessarily born with clean slates. For example, they remember some sounds which they heard in the mother's womb. Sounds in the womb are usually muffled, but the melody and rhythm of musical sounds are not much altered. 3 Surprisingly, babies sometimes can naturally do what adults think babies cannot do. Do you believe that babies are born with the ability to hold their 15 breath in the water and swim? Some researchers studying the dive reflex in 21 infants between four and twelve months old found that none of them inhaled water or choked 20 during "diving."

基礎問 58 直線の傾きとtangent (1) x軸の正方向と 75°をなす直線の傾きを求めよ. (2) 2直線y=0 (x軸) と y=2x のなす角を2等分する直線の うち,第1象限を通るものを求めよ. (1) 直線の傾きmと, 直線がx軸の正方向となす角 0 の間には m=tan0 の関係があります. とても大切な関係式ですが,本間 はこれだけでは答えがでてきません. それは tan 75° の値を知ら ないからです.しかし, sin 75° や cos 75° ならば, 75°= 45°+30°と考えれば 5の加法定理が使えます.だから,ここでは tangent の加法定理 (ポイント) を利用します. 精講 (2) 求める直線をy=mx, m=tan0 とおいて,図をかくと, tan202 をみ たす m(または tan0) を求めればよいことがわかります.このとき,2倍角 の公式 (ポイント) が必要です. 解答 tan 45°+tan 30° 1-tan 45° tan 30° (1) tan 75°=- = 1+tan 30° 1-tan 30° 1+ 1- 1 √√3 1 √√3 tan 20=2 = = 2+√3 注 75°=120°45°と考えることもできます.
