Re: Temperature Conversion

Here's the equation you need to convert from Fahrenheit to Celsius:

C * (9/5) + 32 = F

Plug in 101.8 for F, and solve for C:

C * (9/5) + 32 = 101.8

Differential Equations with 1/x

Say you have a differential equation like this: (1/y)dy = dx When you integrate both sides, you get this: ln|y| = x + C Taking e to the both sides... |y| = e^(x + C) From here, my teacher says that the answer would simply be y = e^(x + C). However, taking a simpler situation involving absolute value...
