Whakaoti mō x, y, z
z=u
Tohaina
Kua tāruatia ki te papatopenga
y=u \frac{x-3}{x+1}=\frac{x+2}{x-4} z=y
Me raupapa anō ngā whārite.
z=u
Whakakapia te u mō te y i te whārite z=y.
x=1
Me whakaoti te \frac{x-3}{x+1}=\frac{x+2}{x-4} mō x.
x=1 y=u z=u
Kua oti te pūnaha te whakatau.
Ngā Tauira
whārite tapawhā
{ x } ^ { 2 } - 4 x - 5 = 0
Āhuahanga
4 \sin \theta \cos \theta = 2 \sin \theta
whārite paerangi
y = 3x + 4
Arithmetic

whārite Simultaneous
\left. \begin{cases} { 8x+2y = 46 } \\ { 7x+3y = 47 } \end{cases} \right.
Whakarerekētanga
\frac { d } { d x } \frac { ( 3 x ^ { 2 } - 2 ) } { ( x - 5 ) }
Whakaurunga
\int _ { 0 } ^ { 1 } x e ^ { - x ^ { 2 } } d x
Ngā Tepe
