SUMMARY

The forum discussion centers on a mathematical problem where the user arrives at a different answer than presented in a book. The user questions the validity of the equation \(\frac{1}{1 + 1} = \frac{1}{1} + \frac{1}{1}\) and highlights that the integral of \(\csc(x) \cdot \sec^2(x) \, dx\) does not equal the original integral. Additionally, the user points out that \( \frac{1}{1 - \cos^2(x)} \) does not equal \( \frac{1}{\cos^2(x)}\), suggesting a potential oversight in the calculations.

PREREQUISITES
  • Understanding of basic algebraic equations

Hello, here I worked a problem out and got a different answer than the book gave so I was wondering if it looks correct or not.

Thanks for the help

You could always try plugging in a few values for x to see...


Anyways... does

[tex]\frac{1}{1 + 1} = \frac{1}{1} + \frac{1}{1}[/tex]

?
 
integral(cscx*sec^2(x)dx) does not equal the original integral.

1/(1-cos^2(x)) does not equal 1/cos^2(x)
you probably overlooked the one. :smile: :wink:
