I have a very complex math formula/equation which involves exponential.
X + 2 = Y
*PS: The above is just an example to illustrate my problem. The real formula is way more complex than this.
There is no way for me to form an equation with X variable on the left like
X = Y - 2. I tried professional Math software like
Mathematica to solve the equation but failed.
I was given the value of Y, how can I find/estimate the value of X?
My current idea is start looping X = 1 and increase X's value with a fixed increment in each loop and try to match my value Y. The only relationship I have now is that the greater value of X generates a smaller value of Y.
Is there any good algorithm out there for my problem?
