\(tan(sin^{-1}A)=\frac{cos^2B(tan^4B-1)+1}{tan^2B}\)

Hi Max,

If you enter it in a form that I can just copy and past then I will enter it into Wolfram Alpha for you :)

(that means  no   LaTex)

What is 145?

Your question does not make sense!

That guest is joking.

This site is totally free.  

You do not have to but it is better if you sign up and get known.  :)

I agree. That is weird.

But CPhill and guest are both correct

Some nimber plus 30% is ambiguous.  30 % of what?

If you want 15.99 + 30% of 15.99

Then ypu should have tje skill to enter this as. 15.99 + 0.30×15.99

Yes,

It is a straight line and it is not vertical so it is a function :)

Hi Ginger

You know I saw you logged on.  Then  I saw you had logged off.

Next these 'anonymous' posts appeared.  I knew immediately that you had posted them.  I wondered why you did that but I just guessed that you were of 2 minds about claiming your written creation. :)

I would have known that they were your words even if you had not logged on.  It is not always as easy to hide as people think. :)

Anyway it is nice you are here, I am nostalgic too:)

LOL

I bet the cat did a good job.

Is it stumbling around with head in paws or is it sleeping it off in a cosy corner?   

How many black queens are in the pack?  Divide that number by 52 

That is pretty cool Max!

Yes it would take a while. LOL.
