Question

Как из этой формулы выразить t2. r1/r2=1+alphat1\1+alphat2

Answer 1

$\frac{ R_{1} }{R_{2}}= \frac{1+ \alpha t_{1}}{1+ \alpha t_{2}} \\ \\ R_{2}+R_{2} \alpha t_{1}=R_{1}+R_{1} \alpha t_{2} \\ \\ t_{2}= \frac{R_{2}+R_{2} \alpha t_{1}-R_{1}}{R_{1} \alpha } \\ \\ t_{2}= \frac{R_{2}-R_{1}}{R_{1} \alpha }+ \frac{R_{2}t_{1}}{R_{1}}$

Answer 2

$\frac{R_1}{R_2} = \frac{1+at1}{1+at2} \\ \\ 1+at_2= \frac{R_2(1+at1)}{R_1} \\ \\ at_2= \frac{R_2(1+at1)}{R_1}-1= \frac{R_2(1+at1)-R_1}{R_1} \\ \\ t_2= \frac{R_2(1+at1)-R_1}{aR_1}$
