Trigonometry yog ib ceg ntawm kev ua lej uas kawm txog peb tog thiab lub voj voog. Trigonometric functions tau siv los piav qhia txog cov yam ntxwv ntawm cov ces kaum, kev sib raug zoo hauv cov duab peb sab, thiab cov duab ntawm kev rov ua dua. Kev kawm trigonometry yuav pab koj nkag siab, nrog rau kev pom thiab teeb duab cov kev sib raug zoo no thiab mus. Yog tias koj ua ke kev kawm tus kheej nrog kev mob siab rau hauv chav kawm, koj yuav nkag siab cov ntsiab lus yooj yim ntawm trigonometry thiab yuav pib nkag siab cov voj voog hauv ntiaj teb ib puag ncig koj.

Kauj Ruam 1. Txheeb xyuas qhov seem ntawm daim duab peb sab

Hauv qhov tseem ceeb, trigonometry yog kawm txog kev sib raug zoo uas muaj nyob hauv daim duab peb sab. Ib daim duab peb sab muaj peb sab thiab peb lub kaum. Los ntawm kev txhais, qhov sib npaug ntawm cov ces kaum ntawm txhua daim duab peb sab yog 180 degrees. Koj yuav tsum paub koj tus kheej nrog daim duab peb sab thiab lawv cov lus kom ua tiav hauv trigonometry. Qee cov ntsiab lus sib npaug rau daim duab peb sab yog:

  • Hypotenuse Qhov ntev tshaj plaws ntawm daim duab peb sab.
  • Obtuse angle Ib lub kaum sab xis uas siab dua 90 degrees.
  • Acute angle Ib lub kaum sab xis uas qis dua 90 degrees.

Kauj Ruam 2. Kawm ua ib lub voj voog

Lub voj voog tsev cia koj ntsuas txhua daim duab peb sab kom nws qhov hypotenuse sib npaug rau ib qho. Lub tswv yim no muaj txiaj ntsig ntsig txog kev ua haujlwm trigonometric, xws li sine thiab cosine, rau feem pua. Thaum koj nkag siab lub voj voog tsev, koj tuaj yeem siv qhov ntsuas trigonometric rau qee cov ces kaum los teb cov lus nug txog peb tog uas muaj cov ces kaum.

  • Piv txwv 1: Lub kaum sab xis ntawm 30 degree yog 0.50.
  • Piv txwv 2: Qhov kev sib raug zoo no tuaj yeem siv los nrhiav qhov ntev ntawm qhov hypotenuse ntawm daim duab peb sab uas muaj lub kaum sab xis ntawm 30 degrees thiab qhov ntev ntawm ib sab yam sib txawv lub kaum sab xis yog 18 cm. Qhov hypotenuse yog 36 cm.

Kauj Ruam 3. Nkag siab txog kev ua haujlwm trigonometric

Muaj rau rau lub luag haujlwm tseem ceeb hauv kev nkag siab trigonometry. Ua ke ua ke, cov haujlwm rau no txhais qhov kev sib raug zoo hauv ib daim duab peb sab, thiab tso cai rau koj kom nkag siab cov yam ntxwv tshwj xeeb ntawm txhua daim duab peb sab. Rau lub luag haujlwm yog:

  • Sine (zeeg)
  • Cosine (zeeg)
  • Tangent (Tan)
  • Secan (zeeg)
  • Cosecant (Csc) Cov
  • Cotangent (Cot)

Kauj Ruam 4. Nkag siab qhov sib piv ntawm cov haujlwm trigonometric

Ib qho tseem ceeb tshaj plaws kom nkag siab txog trigonometry yog tias txhua txoj haujlwm muaj feem cuam tshuam. Txawm hais tias qhov txiaj ntsig ntawm sine, cosine, tangent, thiab lwm yam, muaj lawv tus kheej siv. Qhov txiaj ntsig tseem ceeb tshaj plaws yog kev sib raug zoo ntawm txhua txoj haujlwm no. Lub tswv yim ntawm ib lub voj voog tsev ua rau kev txheeb ze nkag siab yooj yim dua. Thaum koj nkag siab lub voj voog tsev, koj tuaj yeem siv cov kev sib raug zoo piav los ntawm lub voj voog tsev los tsim cov qauv rau lwm yam teeb meem.

Kauj Ruam 1. Nkag siab qhov siv yooj yim ntawm trigonometry hauv cov ntsiab lus kev kawm

Ntxiv rau kev kawm trigonometry rau kev lom zem, cov lej thiab kws tshawb fawb tau siv lub tswv yim no tiag. Trigonometry tuaj yeem siv los nrhiav tus nqi ntawm cov ces kaum lossis kab ntu. Koj kuj tseem tuaj yeem piav qhia tus cwj pwm los ntawm kev piav qhia nws ua haujlwm trigonometric.

Piv txwv li, cov lus tsa suab ntawm lub caij nplooj ntoo hlav rov qab tuaj yeem piav qhia los ntawm kev piav qhia nws li sine yoj

Kauj Ruam 2. Xav txog kev mus los ntawm xwm

Qee zaum, tib neeg muaj teeb meem nkag siab cov ntsiab lus paub daws teeb meem hauv lej lossis tshawb fawb. Yog tias koj paub tias cov tswv yim no muaj nyob hauv ntiaj teb ib puag ncig koj, koj yuav nquag pom lawv los ntawm kev xav tshiab. Nrhiav cov khoom nyob ib puag ncig koj uas txav mus los, tom qab ntawd sim txheeb lawv rau cov ntsiab lus trigonometric.

Kauj Ruam 3. Pom tau tias yuav kawm txog kev mus los li cas

Thaum koj paub tias qhov xwm txheej puv puv, pib xav txog txoj hauv kev los kawm nws. Xav txog cov qauv duab los piav qhia txog lub voj voog no. Los ntawm kab ntawv, koj tuaj yeem tsim qhov sib npaug los piav qhia qhov tshwm sim pom. Ib qho ntxiv, trigonometric functions yuav muaj lub ntsiab lus los pab koj nkag siab lawv cov txiaj ntsig.

Xav txog tej yam koj tab tom ntsuas nthwv dej ntawm ib lub puam. Thaum lub sijhawm nthwv dej siab, nthwv dej yuav ncav cuag qhov siab. Tom qab ntawd, nthwv dej yuav thim rov qab kom txog thaum nws mus txog qhov chaw ib yam nkaus. Los ntawm cov dej qis, dej yuav rov nce ntxiv mus rau lub puam kom txog thaum nws nce mus txog qhov siab ntawm nthwv dej siab. Lub voj voog no yuav mus tas li yam tsis muaj qhov kawg, thiab tuaj yeem piav qhia ua haujlwm trigonometric, piv txwv li yog cosine yoj

Kauj Ruam 1. Nyeem tshooj trigonometry

Rau qee tus neeg, cov ntsiab lus ntawm trigonometry nyuaj rau nkag siab thaum xub thawj. Yog tias koj nyeem tshooj trigonometry ua ntej nws tau qhia hauv chav kawm, koj yuav paub cov ntaub ntawv ntau dua. Ntau zaus koj saib cov ntaub ntawv, ntau qhov kev sib txuas koj tuaj yeem ua txog kev sib raug zoo ntawm cov ntsiab lus sib txawv hauv trigonometry.

Nws tseem tso cai rau koj txheeb xyuas cov ntsiab lus trigonometric ua ntej peb ntsib teeb meem hauv chav kawm

Kauj Ruam 4. Txuas ntxiv koj cov dag zog los ntawm kev ua cov lus nug ntxiv

Ua kom tiav txhua cov ntawv ua tom tsev. Cov lus nug hauv tsev yog cov lus qhia zoo rau cov lus nug xeem. Xyuas kom koj nkag siab txhua lo lus nug. Yog tias koj tus kws qhia ntawv tsis ua homework, sim ua cov lus nug uas muaj cov ntsiab lus nthuav tawm ntawm lub rooj sib tham zaum kawg hauv koj phau ntawv.

Lub tswv yim

  • Nco ntsoov tias lej yog ib txoj hauv kev xav, tsis yog sau cov qauv los ua cim.
  • Rov kawm algebraic thiab geometric cov ntsiab lus.

Ceeb toom

  • Koj tsis tuaj yeem kawm trigonometry los ntawm kev yuam koj tus kheej los cim. Koj yuav tsum nkag siab cov ntsiab lus.
  • Nws yog qhov tsawg rau txhua tus neeg kom ua tiav qhov ntsuas trigonometry tsuas yog los ntawm kev sau cov khoom txhua hmo.
