tan是什么意思

tan是三角函數(shù)里的正切。英文tangent的縮寫(xiě)。

tan是什么意思

  題目的答案依次是三分之根號(hào)三，一根號(hào)三以及無(wú)窮大。這個(gè)問(wèn)題的考點(diǎn)是在三角函數(shù)的地方，tan用漢語(yǔ)來(lái)講的話其實(shí)就是正切值。有的人可能不怎么了解什么叫做正切值，這個(gè)詞其實(shí)就是數(shù)學(xué)的中的專有名詞，想要了解的話可以去看向的章節(jié)。

三角函數(shù)主要是出現(xiàn)在高中的課本當(dāng)中，如果是大學(xué)的三角函數(shù)的話就比高中要高級(jí)得多。但是其實(shí)只要掌握了高中的三角函數(shù)的話，那么大學(xué)我相信大家也還是可以學(xué)習(xí)到精華的。那我們現(xiàn)在講一下就是三角函數(shù)的出題，一般在高考試卷當(dāng)中的第一個(gè)大題會(huì)出現(xiàn)三角函數(shù)，但是這不是絕對(duì)的，因?yàn)榈谝粋€(gè)答題的題目的設(shè)定是有兩個(gè)題型的，一個(gè)是等比數(shù)列的那一節(jié)的，考點(diǎn)還想一般是它的一些公式或者是特殊的數(shù)值的考點(diǎn)。

  另一個(gè)題型就是我們現(xiàn)在這個(gè)題目當(dāng)中的三角函數(shù)，其實(shí)這個(gè)函數(shù)值是三角函數(shù)當(dāng)中的基礎(chǔ)中的基礎(chǔ)，只有覺(jué)得這些值也有可能算的對(duì)題目，因?yàn)橐话憧荚嚨臅r(shí)候這些值都是不給的，那么記不住就算不出來(lái)。所以記住這些數(shù)字就比較重要了，正切也還只是這幾數(shù)值當(dāng)中的的一個(gè)，其實(shí)還有正旋值和余旋值也是大家必須記住的，還有就是在學(xué)習(xí)這一章的時(shí)候其實(shí)是可以結(jié)合圖形來(lái)學(xué)習(xí)的，因?yàn)檫@些數(shù)字的原來(lái)是有依據(jù)的。

其實(shí)在高考當(dāng)中的話，三角函數(shù)的考點(diǎn)不僅僅只是這些簡(jiǎn)單的數(shù)值，這些也只是基礎(chǔ)。要懂的知識(shí)點(diǎn)是三角函數(shù)的計(jì)算，因?yàn)槠鋵?shí)考試的時(shí)候題型的設(shè)定就是為了讓大家了解這些數(shù)學(xué)問(wèn)題的計(jì)算，而這些數(shù)學(xué)問(wèn)題的基礎(chǔ)其實(shí)就是書(shū)本，所以大家要讀看書(shū)，哪怕是數(shù)學(xué)書(shū)。
