Lub laij lej raug muaj peb trig muaj nuj nqi Yog tias nws muaj ib qho: sine, cosine, thiab tangent. Lwm qhov peb uas koj tuaj yeem pom - cosecant, secant, thiab cotangent - yog cov reciprocals ntawm sine, cosine, thiab tangent feem.

Ntxiv mus, muaj pes tsawg hom kev ua haujlwm trigonometric muaj?

Muaj rau lub ntsiab trigonometric functions:

Sine (kev txhaum)
Cosine (zeeg)
Tangent (zeeg)
Secant (sec)
Cosecant (tsim)
Cotangent (zeeg)

3 trig functions yog dab tsi? Peb lub luag haujlwm tseem ceeb hauv trigonometry yog Sine , Cosine thiab Tangent . Qhov ntawd yog peb thawj Trigonometric Identity.

Qhov thib ob, 6 trig functions yog dab tsi?

Rau txhua txoj cai daim duab peb sab, muaj rau trig ratios: Sine ( kev txhaum ), cosine ( cos tangent (tawm), cosecant (csc), secant (sec), thiab cotangent ( cot ).

CSC yog dab tsi ntawm kev txhaum thiab cos?

Lub tangent ntawm x txhais tau tias yog nws cov sine faib los ntawm nws cov cosine: Cov cotangent ntawm x txhais tau tias yog cosine ntawm x muab faib los ntawm sine ntawm x: cot x = cos x kev txhaum x. Lub secant ntawm x yog 1 muab faib los ntawm cosine ntawm x: sec x = 1 cos x, thiab cov cosecant ntawm x txhais tau tias yog 1 muab faib los ntawm sine ntawm x: csc ua x = 1 kev txhaum x.

Muaj pes tsawg protons neutrons thiab electrons 58 28ni muaj?

Ni-58 muaj atomic tooj ntawm 28 thiab ib tug loj tus naj npawb ntawm 58. Yog li ntawd, Ni-58 yuav muaj 28 protons, 28 electrons, thiab 58-28, los yog 30, neutrons.Ni-60 2+ hom, tus naj npawb ntawm Protons zoo ib yam li hauv nruab nrab Ni-58

Muaj pes tsawg lub hauv paus zoo tuaj yeem muaj qhov sib npaug?

Ib txoj hauv kev los txiav txim siab qhov siab tshaj plaws ntawm qhov zoo thiab qhov tsis zoo ntawm cov hauv paus ntsiab lus ntawm polynomial. Txij li thaum muaj peb qhov kev hloov pauv, muaj qhov siab tshaj plaws ntawm peb lub hauv paus zoo

Muaj pes tsawg guanine bases puas yog 50 lub hauv paus khub ob txoj hlua DNA 100 bases tag nrho muaj yog tias nws muaj 25 adenine bases?

Yog li, muaj tag nrho ntawm 25 + 25 = 50 adenine thiab thymine hauv tag nrho. Qhov ntawd tawm 100− 50 = 50 seem hauv paus. Nco ntsoov tias cytosine thiab guanine daim ntawv cog lus nrog ib leeg, thiab yog li lawv sib npaug ntawm cov nyiaj. Tam sim no peb tuaj yeem faib los ntawm 2 kom tau txais tus lej ntawm guanine lossis cytosine hauv paus

Dab tsi quadrant yog inverse trig functions nyob rau hauv?

Lub inverse cos, sec, thiab cot functions yuav rov qab muaj nuj nqis nyob rau hauv lub I thiab II Quadrants, thiab cov inverse sin, csc, thiab tan functions yuav rov qab muaj nuj nqis nyob rau hauv lub I thiab IV Quadrants (tab sis nco ntsoov tias koj xav tau qhov tsis zoo qhov tseem ceeb hauv Quadrant IV. )
