Tus tangent piv yog y / x, yog li qhov tangent yuav tsis zoo thaum x thiab y muaj cov cim qhia. Qhov no tshwm sim hauv thib ob quadrant(qhov twg x yog qhov tsis zoo tab sis y yog qhov zoo) thiab hauv plaub plaub (qhov twg x yog qhov zoo tab sis y yog qhov tsis zoo).
Dab tsi quadrants muaj qhov tsis zoo tangent?
thib peb quadrant thiab plaub plaub. Daim ntawv ceeb toom tias qhov tseem ceeb ntawm tangent yog qhov zoo nyob rau hauv qhov thib peb quadrant, vim tias ob qho tib si sine thiab cosine yog qhov tsis zoo. Tus nqi ntawm tangent yog qhov tsis zoo hauv thib ob thiab plaub plaub.
Puas yog Tan tsis zoo nyob rau hauv 4th quadrant?
Nyob rau hauv qhov thib ob quadrant (II), sine (thiab cosec) yog qhov zoo. Hauv qhov thib peb quadrant (III), tan (thiab cotan) yog qhov zoo. Hauv plaub plaub (IV), cos (thiab sec) yog qhov zoo.
Qab quadrant yog tan zoo?
Nyob rau hauv plaub plaub, Cos yog qhov zoo, thawj zaug, Txhua tus yog qhov zoo, hauv qhov thib ob, Kev txhaum yog qhov zoo thiab thib peb quadrant, Tan yog qhov zoo.
Puas Tan zoo nyob rau hauv quadrant 2?
Txhua txoj haujlwm trig yog qhov zoo hauv Quadrant 1. Sine thiab cosecant yog qhov zoo hauv Quadrant 2, tangent thiab cotangent yog qhov zoo hauv Quadrant 3, thiab cosine thiab secant yog qhov zoo hauv Quadrant 4.
