Math Domain Error In Python

Math domain error in python. Python math acos function is used to find arc cosine. Its either or you only do. The function is under the python math library and we have to import the math library before using it. Learn how to fix valueerror.

The cosine of an angle is always in the range 1 0 1 0 so the inverse function is only defined for inputs in that range you re giving acos a value larger than 1. Math sqrt can t handle a negative value. Math domain error 原因 某些操作不符合数学定义 如对负数取对数 对负数开平方.

There s no possible real angle whose cosine is greater than 1. Traceback most recent call last. Mark dickinson jun 20 15 at 14 29. When i run that code below i get the following error.

I was testing the math module and pil module and trying to apply a box count algorithm on a image. File c users joao desktop image size py line 48 in module gy append math log boxcount valueerror. So if you make b high for example 9 and a and c low 1 and 2 for example it works its been a while since i used this but looking at this image from wikipedia there are two possible outcomes. The math acos function takes a number between 1 to 1 and finds the arc cosine of that number.

Math domain error that comes while working in python.
