考研高数公式总结

·平方关系:

sin^2(α)+cos^2(α)=1

tan^2(α)+1=sec^2(α)

cot^2(α)+1=csc^2(α)

·积的关系:

sinα=tanα*cosα

cosα=cotα*sinα

tanα=sinα*secα

cotα=cosα*cscα

secα=tanα*cscα

cscα=secα*cotα

·倒数关系:

·三角函数恒等变形公式

·两角和与差的三角函数:

cos(α+β)=cosα·cosβ-sinα·sinβ

cos(α-β)=cosα·cosβ+sinα·sinβ

sin(α±β)=sinα·cosβ±cosα·sinβ

tan(α+β)=(tanα+tanβ)/(1-tanα·tanβ)

tan(α-β)=(tanα-tanβ)/(1+tanα·tanβ)

·三角和的三角函数:

sin(α+β+γ)=sinα·cosβ·cosγ+cosα·sinβ·cosγ+cosα·cosβ·sinγ-sinα·sinβ·sinγ

cos(α+β+γ)=cosα·cosβ·cosγ-cosα·sinβ·sinγ-sinα·cosβ·sinγ-sinα·sinβ·cosγ

tan(α+β+γ)=(tanα+tanβ+tanγ-tanα·tanβ·tanγ)/(1-tanα·tanβ-tanβ·tanγ-tanγ·tanα)

·辅助角公式:

Asinα+Bcosα=(A^2+B^2)^(1/2)sin(α+t),其中

sint=B/(A^2+B^2)^(1/2)

cost=A/(A^2+B^2)^(1/2)

tant=B/A

Asinα+Bcosα=(A^2+B^2)^(1/2)cos(α-t),tant=A/B

·倍角公式:

sin(2α)=2sinα·cosα=2/(tanα+cotα)

cos(2α)=cos^2(α)-sin^2(α)=2cos^2(α)-1=1-2sin^2(α)

tan(2α)=2tanα/[1-tan^2(α)]

·三倍角公式:

sin(3α)=3sinα-4sin^3(α)

cos(3α)=4cos^3(α)-3cosα

·半角公式:

sin(α/2)=±√((1-cosα)/2)

cos(α/2)=±√((1+cosα)/2)

tan(α/2)=±√((1-cosα)/(1+cosα))=sinα/(1+cosα)=(1-cosα)/sinα

·降幂公式

sin^2(α)=(1-cos(2α))/2=versin(2α)/2

cos^2(α)=(1+cos(2α))/2=covers(2α)/2

tan^2(α)=(1-cos(2α))/(1+cos(2α))

·万能公式:

sinα=2tan(α/2)/[1+tan^2(α/2)]

cosα=[1-tan^2(α/2)]/[1+tan^2(α/2)]

tanα=2tan(α/2)/[1-tan^2(α/2)]

·积化和差公式:

sinα·cosβ=(1/2)[sin(α+β)+sin(α-β)]

cosα·sinβ=(1/2)[sin(α+β)-sin(α-β)]

cosα·cosβ=(1/2)[cos(α+β)+cos(α-β)]

sinα·sinβ=-(1/2)[cos(α+β)-cos(α-β)]

·和差化积公式:

sinα+sinβ=2sin[(α+β)/2]cos[(α-β)/2]

sinα-sinβ=2cos[(α+β)/2]sin[(α-β)/2]

cosα+cosβ=2cos[(α+β)/2]cos[(α-β)/2]

cosα-cosβ=-2sin[(α+β)/2]sin[(α-β)/2]

·推导公式

tanα+cotα=2/sin2α

tanα-cotα=-2cot2α

1+cos2α=2cos^2α

1-cos2α=2sin^2α

1+sinα=(sinα/2+cosα/2)^2

·其他:

sinα+sin(α+2π/n)+sin(α+2π*2/n)+sin(α+2π*3/n)+……+sin[α+2π*(n-1)/n]=0

cosα+cos(α+2π/n)+cos(α+2π*2/n)+cos(α+2π*3/n)+……+cos[α+2π*(n-1)/n]=0 以及sin^2(α)+sin^2(α-2π/3)+sin^2(α+2π/3)=3/2

部分高等内容

·高等代数中三角函数的指数表示(由泰勒级数易得):

sinx=[e^(ix)-e^(-ix)]/(2i) cosx=[e^(ix)+e^(-ix)]/2 tanx=[e^(ix)-e^(-ix)]/[ie^(ix)+ie^(-ix)]

泰勒展开有无穷级数,e^z=exp(z)=1+z/1!+z^2/2!+z^3/3!+z^4/4!+…+z^n/n!+… 此时三角函数定义域已推广至整个复数集。

·三角函数作为微分方程的解:

对于微分方程组y=-y'';y=y'''',有通解Q,可证明

Q=Asinx+Bcosx,因此也可以从此出发定义三角函数。

补充:由相应的指数表示我们可以定义一种类似的函数——双曲函数,其拥有很多与三角函数的类似的性质,二者相映成趣。

16天记忆7000考研单词(完整版-带注释)

友情提供:“背句子学单词”,一起加油,一起享受奋斗的过程!不管结果怎么样,养成一种积极向上的习惯对人生始终是有益无害的。 ——让你16天学会7000考研单词 单词是构建语言大楼的砖石! 如果把语言比作一座大楼,成千上万的单词就是构成这座大楼的砖块。掌握一定量的单词是阅读、听力、 写作、口语以及翻译的基础。此外,语言是一个内部紧密联系的整体,单词恰似语言这张错综复杂的网络 上的结点。词与词之间的关系有:约束关系(例如人称和动词的变化,He is a good boy. But I am a bad girl.), 同义关系(smile, laugh),反义关系(approve, disapprove),派生关系(base, basement),搭配关系(固定短 语fall in love with、成语 Every dog has his day )等等。因此,学习单词不在于将单个词语牢记于胸,重点 是掌握词与词之间的关系。单词可以组成:词语(一个单词black,多个单词blackboard, ad hoc)、短语(或搭配 take a break)、句子以及篇章四种语言单位。 下面介绍几种“背句子记单词”的方法,也算是该电子书的使用指南吧,遵循这些学习方法可以使您达到更 好地学习效果。 方法一:背句子记单词 通常记单词的方法有:第一种,死记硬背型,背单词书;第二种,背诵文章,方法虽好,但耗时费力,不 容易坚持下来;第三种,背句子记单词,也是近年来的趋势。在句子中,单词的用法、搭配、词性(褒贬)能够得到完整地体现,能提供完整的语境。例如: I believe my brief words will relieve her grief. 我相信我简短的话会减轻她的悲痛。 在这个只有 9 个单词的句子中,believe,brief,relieve,grief 四个常用单词的经典用法都体现出来了,即: I believe (我相信,我认为) brief words(简短的话) relieve (+ pain 减轻疼痛) grief (悲痛) 背一个句子,学 4-5 个单词,其高效和省力是显而易见的。 方法二:“五官开动” 在学习英语的时候,还应该“五官开动”,即眼、口、耳、手、脑并用。友情提供版《16天学会7000考研单词》为每个句子和单词都配备了语言发声功能,只要单击图标,就会自动发声。读者可以通过读音来记单词,并纠正发音,可谓一举多得。 方法三:比较记忆法 背单词的时候最容易混淆形近词,例如: The necklace placed in the palace is replaced first, and displaced later. 放在宫殿里的项链先是被偷梁换柱,后来又被转移了。Place [ pleis ] n. 地方,处境,职务 v. 放置,任命,安排 Replace [ ri(:)'pleis ] v. 取代

The dust in the industrial zone frustrated(挫败, 阻挠, 使感到灰心) the industrious(勤勉、刻苦) man. 工业区里的灰尘使勤勉的人灰心. 10. The just budget judge just justifies(证明……是正当的) the adjustment of justice. 公正的预算法官只不过为司法调整辩护而已。 11. I used to abuse the unusual usage, but now I'm not used to doing so. 我过去常滥用这个不寻常的用法,但我现在不习惯这样做。 12. The lace(带子) placed in the palace is replaced first, and displaced later. 放在皇宫的带子先被替换,后来被转移。 13. I paced in the peaceful spacecraft. 我在宁静的宇宙飞船里踱步. 14.
