I just read the longer ealier post made by the same of maybe  a different guest.

Paraphrasing here "Mathematical induction uses  deductive not inductive reasoning".  Yes, maybe LOL

Whoevere said mathematics can't be funny.   

That is strong words coming from someone who will not dientify him/herself. !

Sometimes a word that is used in  the precise language of mathematics

can be used very differently to how it is used in its non-mathematical context.

Maybe another mathematician who is more knowledgable than me would like to have input here. 

Thanks Geno, 

I did not know that!!     I shall try and remember. 

So when we prove by induction then we are proving based on what has come before.  Mmm 

It beats me why this is titled "geometry"

I just realised, you answered your own question.   LOL

I think Alexis made a bit of a slip there.

A negative number divided (or multiplied) with a paositive number is ALWAYS a negative number.

Just remember that when you multiply or divide,  if the SIGNS are DIFFERENT the the answer is NEGATIVE,

Just remember that when you multiply or divide,  if the SIGNS are THE SAME the the answer is POSITIVE

Hello Shelby,

The gradient and y intercept form of a line is      y=mx+b

where m is the gradient and b is the  y intercept.

Perhaps you would like to ask a more specific questrion?

what is the limit of (1-x) tan(pi*x/2) as x approaches infinity

Looking at the graph I would say it was undefined.

(But then I am hopeless at limits)

That is a really good answer guest.    Thanks

Great pic Chris.   

What random number?

What does 12 to the second power mean?
