ln [1.70E-2] = ln(0.144) - (k s-1)(3609 s)

If you know what the formula is, but can't figure out which buttons to press, I suggest that you sit down with your calculator manual and spend a few days going through the examples they will surely have.

I remember when I got my first slide rule. *gasp* I spent two weeks just going through the manual. After that, I knew the machine inside and out.
