Cotangent , Secant thiab Cosecant . Cosecant yog qhov sib txuam ntawm sine. Secant yog qhov sib txuam ntawm cosine. Cotangent yog qhov sib txuam ntawm tangent. Thaum daws txoj cai triangles peb lub ntsiab yog ib txwm siv.
Yog li ntawd, qhov txawv ntawm Secant thiab Cosecant yog dab tsi?
Cosecant Graph Yog li, peb muaj cosecant (csc) yog qhov sib txuam ntawm sine lossis 1 / sine, secant (sec) yog reciprocal ntawm cosine los yog 1/cosine, thiab cotangent (cot) yog reciprocal ntawm tangent muaj nuj nqi los yog 1/tangent. Lub tangent thiab cotangent yog ib qho yooj yim rau nco ntsoov vim lawv qhia tib lo lus 'tangent.
Ib sab saum toj no, tangent cotangent secant thiab Cosecant cuam tshuam li cas rau sine thiab cosine? Cov cosecant yog qhov sib txawv ntawm cov sib . Cov secant yog qhov sib txawv ntawm cov cosine . Cov cotangent yog qhov sib txawv ntawm cov tangent.
Hauv qhov no, Cosecant sib npaug li cas?
Cosecant ( csc ua ) - Trigonometry muaj nuj nqi Hauv daim duab peb sab txoj cai, lub cosecant ntawm lub kaum sab xis yog qhov ntev ntawm lub hypotenuse muab faib los ntawm qhov ntev ntawm sab nraud. Nyob rau hauv ib tug formula, nws yog abbreviated rau xwb ' csc ua '. Lawv tuaj yeem hloov tau yooj yim nrog derivations ntawm ntau yam peb: kev txhaum, cos thiab tan.
Puas yog Cos tib yam li SEC?
Secant, cosecant thiab cotangent, yuav luag ib txwm sau li sec , cosec thiab cot yog trigonometric functions xws li kev txhaum, cos thiab tan. Nco tseg, sec x tsis yog ib yam raws li cos -1x (qee zaum sau ua arccos x). Nco ntsoov, koj tsis tuaj yeem faib los ntawm xoom thiab yog li cov ntsiab lus no tsuas siv tau thaum cov denominators tsis yog xoom.

Sociobiology yog dab tsi thiab dab tsi yog qhov kev thuam loj ntawm nws?
Ib feem ntawm sociobiology cuam tshuam nrog kev coj tus cwj pwm tsis zoo feem ntau. Cov neeg thuam tau hais tias daim ntawv thov ntawm sociobiology no yog ib hom kev txiav txim siab caj ces thiab nws ua tsis tau raws li qhov nyuaj ntawm tib neeg tus cwj pwm thiab qhov cuam tshuam ntawm ib puag ncig ntawm tib neeg txoj kev loj hlob
Dab tsi yog cov reagents xav tau rau PCR thiab dab tsi yog qhov ua haujlwm ntawm txhua tus?
Muaj tsib yam tshuaj reagents, lossis cov khoom xyaw, siv hauv PCR: qauv DNA, PCR primers, nucleotides, PCR tsis thiab Taq polymerase. Primers feem ntau yog siv nyob rau hauv khub, thiab DNA ntawm ob lub primers yog amplified thaum lub sij hawm PCR cov tshuaj tiv thaiv
Dab tsi yog qhov txawv ntawm Marine West Coast huab cua thiab dab tsi yog lub luag haujlwm rau cov yam ntxwv ntawd?
Cov ntsiab lus ntawm Marine West Coast Qhov kev nyab xeeb ntawm cov yam ntxwv tseem ceeb yog lub caij ntuj sov me me thiab lub caij ntuj no thiab cov nag lossis daus txhua xyoo. Qhov ecosystem no muaj kev cuam tshuam loj heev los ntawm nws qhov ze rau ntawm ntug dej hiav txwv thiab roob. Nws yog qee zaum hu ua huab cua sab hnub poob ntug dej hiav txwv lossis dej hiav txwv huab cua
Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
