    Hi everybody, I am student of Phd and preparing doctorate thesis. I have this equation y=x-2.438e-4*sqrt((14.17+3163.8*x^(0.655))*Z). how can I solve this equation for three Z values (for example 0.015, 0.025, 0.035). Thank you.

      What has it to do with this forum? BTW, what do you want to solve? I see just a function, namely y(x) there. :)

        Riiiight. And I suppose basic algebra is a post-doctoral topic. :rolleyes:

            Obviously not a science or maths PhD though. I suggest you ask for help in the maths or physics departments, or maybe your supervisor?

              Given an x and a Z, you want to find the value of y using the following equation: y=x-2.438e-4*sqrt((14.17+3163.8*x^(0.655))*Z) This is just a simple expression in C/C++. I don't know where the difficulty lies. Please explain the question more clearly.

                I already have a PhD -- Permanent Head Damage. I feel dizzy now. I also believe this can be solved by a simple expression.

                  Plug in numbers into each variable and see what happens. This may take you O(n^3) amt of time though.
