how to solve for \(T_m\) using a calculator? \[\huge \frac{\ln (\frac{40 - T_m}{70-T_m})}{5} = \frac{\ln (\frac{0.5}{70-T_m})}{35}\]

Is it a simple scientific calculator?
yep
isolate Tm (on the right hand side equation)

hmm?
u will have a equation like: Tm=f(Tm) enter an initial guess to save it in the Ans then enter f(Tm) in ur calculator with Ans instead of Tm then push the Ans Button repeatedly to converge
wahhh i dont get you...go slow please :(
  • phi
you could use newton's method \[ y_{n+1}= y_n - \frac{f(y_n)}{f'(y_n)} \]
wahh? o.O
lol i only need to know how to input this in calculator :C
  • phi
I believe you can only find a solution using a numerical technique, an iterative search that converges on an answer. A bit painful using a calculator. If you just want the solution, use wolfram.
but i need to learn howto use my calculator...hmm will you just tell me how to isolate tm then?
  • phi
you can get to a form like \[ 2(40-T_m)^7=(7-T_m)^6 \] but you can not isolate Tm...
hmm...where did 2 come from again?
  • phi
*70 the 2 from 0.5
oh og course
of course*
@phi are you familiar with the shift + solve in scientific calculators?
  • phi
No, but I assume it can solve equations numerically?
i think so..if i can figure it out...
  • phi
maybe this will help for convenience, let y= 40-x, so the problem can be written as \[2y^7= (y+30)^6 \] \[ 2^{(1/6)}y^{(7/6)}-y-30 = 0 \] now you find the roots of this expression, and then find x= 40-y
hmm i did not get that lol sorry...i'll try doing trial and error on my calculator now
  • phi
what calculator are you using? so I can look at its user manual
canon f-788dx
