Whakaoti mō a
a=e^{\frac{t}{20}}
Whakaoti mō t (complex solution)
t=20\ln(a)-i\times 40\pi n_{1}
n_{1}\in \mathrm{Z}
a\neq 0
Whakaoti mō t
t=20\ln(a)
a>0
Tohaina
Kua tāruatia ki te papatopenga
e^{-\frac{t}{20}}a=1
He hanga arowhānui tō te whārite.
\frac{e^{-\frac{t}{20}}a}{e^{-\frac{t}{20}}}=\frac{1}{e^{-\frac{t}{20}}}
Whakawehea ngā taha e rua ki te e^{-0.05t}.
a=\frac{1}{e^{-\frac{t}{20}}}
Mā te whakawehe ki te e^{-0.05t} ka wetekia te whakareanga ki te e^{-0.05t}.
a=e^{\frac{t}{20}}
Whakawehe 1 ki te e^{-0.05t}.
