In my last physics class, all that was required was to show that a system of eqns was solvable and then I could move on (it was pretty great) - I think some of my simpler math-solving skills have deteriorated as a result. I should also mention that I'm also terrible at solving systems of equations. I can't tell you what I'm trying to solve because I, myself, do not know what I am trying to solve. Ln(approx given x2) = ln(K) + n(ln(approx given y2)) Ln(approx given x1) = ln(K) + n(ln(approx given y1))
If I had to make an educated guess, is there some kind of way to do essentially "u-sub" for the "ln()" version of the equations? i.e. I've taken Calc 1 and 2 and am currently taking Linear Algebra (not acting like I completely know what's going on in this class tho), do I have the tools necessary to solve a system of nonlinear equations (that's what this is, right)?
#Wolframalpha solve for x how to#
That's beside the point - I would like to know how to solve these things without Wolfram. The first few online "system of equations" solvers I used didn't work, but I used wolfram and it worked I think. However, I noticed that the equation is not linear. Well, I would have been more than excited to use the "Least Squares" method from Linear Algebra (the other course I'm taking this summer) to approximate the best values. The textbook pretty much says "hurr durr, two independent equations and two unknowns so- SOLVABLE!" - but that tells me absolutely nothing because it just assumes the values are known from that point in the example problem. I'm given a graph which allows me to find at least two points of data for "E" and for "o". The equation kind of looks like this(I'm making up some of the variables for it): The equation I'm using is called the "steady state creep rate for constant temperature" or something (I'm honestly really confused with this whole section of the textbook, this is for Materials Science by the way).
