系數(shù)、次數(shù)、指數(shù)是什么意思？

代數(shù)式的單項(xiàng)式中的數(shù)字因數(shù)叫做它的系數(shù)(coefficient)。單項(xiàng)式中所有字母的指數(shù)的和叫做它的次數(shù)。簡介：討論數(shù)學(xué)問題時(shí)，在與特定的變量(或未知函數(shù))及其導(dǎo)數(shù)有關(guān)的表達(dá)式或方程中，與未知數(shù)相乘的已知函數(shù)或常數(shù)稱為系數(shù)。在物理學(xué)﹑工程，電腦技術(shù)及其他方面，也廣泛使用系數(shù)這一名詞。如一個(gè)量的部分值與總值之比，或一個(gè)量的變化與另一些量的變化之間關(guān)系式中的某些有關(guān)的數(shù)，都稱系數(shù)。這時(shí)在系數(shù)之前常冠以有關(guān)現(xiàn)象或事物的專名，如"膨脹系數(shù)"﹑"石碳酸系數(shù)"等。單項(xiàng)式中的數(shù)字因數(shù)也叫做這個(gè)單項(xiàng)式的系數(shù).多項(xiàng)式中最高次冪項(xiàng)的因數(shù)叫做這個(gè)多項(xiàng)式的系數(shù)。單項(xiàng)數(shù)中的的數(shù)字因數(shù)為它的系數(shù)。

1.通常系數(shù)不為0.

2.在多項(xiàng)式中含有字母的項(xiàng)，該項(xiàng)的整數(shù)部分稱作是該項(xiàng)的系數(shù)，不含字母的項(xiàng)稱作常數(shù)項(xiàng)。如多項(xiàng)式：4ab-5c+6d-7中，4、-5、6分別是含有字母的項(xiàng)a、b、c、d的系數(shù)，而-7這項(xiàng)不含有字母，所以稱作為常數(shù)項(xiàng)。

3.如式子中沒有數(shù)字，系數(shù)的默認(rèn)情況下是為1或-1。例：-x系數(shù)：-1；x系數(shù)：14.次數(shù)指單項(xiàng)式中所有字母的指數(shù)的和。5.分?jǐn)?shù)的系數(shù)，例：-3πxy÷2的系數(shù)為-3π÷2。

Beta (Coefficient)代表什么

同學(xué)你好，很高興為您解答！

Beta (Coefficient)：貝塔系數(shù)，評估一種證券系統(tǒng)性風(fēng)險(xiǎn)的工具，用以量度一種證券或一個(gè)投資證券組合相對總體市場的波動(dòng)性。

貝塔系數(shù)利用回歸的方法計(jì)算。貝塔系數(shù)1即證券的價(jià)格與市場一同變動(dòng)。貝塔系數(shù)高于1即證券價(jià)格比總體市場更波動(dòng)。貝塔系數(shù)低于1即證券價(jià)格的波動(dòng)性比市場為低。

對于各個(gè)投資領(lǐng)域內(nèi)的專業(yè)人員，包括基金經(jīng)理、證券分析師、財(cái)務(wù)總監(jiān)、投資顧問、投資銀行家、交易員等等，CFA非常重要；它直接證明了你的職業(yè)素養(yǎng)和能力，被投資業(yè)看成一個(gè)“黃金標(biāo)準(zhǔn)”,這一資格被認(rèn)為是投資業(yè)界中具有專業(yè)技能和職業(yè)操守的承諾。考生考過CFA對自己將會(huì)有很大幫助。
