### tan

why tan= opposite/adjacent??

### হিগস বোসন

হিগস বোসন দিয়ে মৌলিক কণিকার ভর ব্যাখ্যা করা যায় । ব্যাপারটা ঠিক বুজতেছি না । মৌলিক কণিকাসমূহের তো নিজস্ব ভর আছেই ।

### Re: Prove me wrong

Avik bhai, I am not sure but as far as i can remember in your book "Mathescop" i have read that , \[0^{-1}= 0\]

but in this discussion I have got that , \[0^{-1}\] is undefined ....Please make it clear...

but in this discussion I have got that , \[0^{-1}\] is undefined ....Please make it clear...

### Re: Prove me wrong

make it clear to me.....which one is correct, \[0^{-1}=\frac{1}{0}or, 0^{-1}=0\]

\[0^{-1}=\frac{1}{0}or, 0^{-1}=0\]

\[0^{-1}=\frac{1}{0}or, 0^{-1}=0\]

### Re: Prove me wrong

I expected this answer...now see, if

\[0^{-1}= \frac{1}{0}\]

then,

\[0 = 0^{1}=0^{2-1}=\frac{0^{2}}{0^{1}}=\frac{0}{0}

so, \frac{0}{0}=0

\]

but 0/0 is undefined..... I am looking for another perfect answer....

\[0^{-1}= \frac{1}{0}\]

then,

\[0 = 0^{1}=0^{2-1}=\frac{0^{2}}{0^{1}}=\frac{0}{0}

so, \frac{0}{0}=0

\]

but 0/0 is undefined..... I am looking for another perfect answer....

### Prove me wrong

0^0 = 0^{1 - 1} = 0^1.0^-1 = 0.0 = 0

I can't get what and where is the mistake ...can anyone help me??
