Yep

@DavidKirby Ok, thanks. I will do try to do it myself

I need point of tangent line

?

So...

I will just find the roots for y = 0

So what we have now? I am lost

x(x-1)=0 ?

Sorry, how should I eliminate that? Can't get it

Yep, where x = 0

Why they should be equal to zero?

@DavidKirby Sorry for confusion.

@DavidKirby So, I have function f(x)=(x-1)arcsinx on [-1,1], and I need to verify somehow that the zero(s) of f represent points where function has tangent lines

And probably I am using wring approach to solve it, may be I don't need to find the root of this equation

Part of it

it's college problem

@DavidKirby thank you anyway. I keep trying.

@DavidKirby I know the root, but I need way to find it

@DavidKirby Exactly

@DavidKirby When you said constant you meant 0 or 1?

@DavidKirby what do you mean?

Can I have one more little hint?

@DavidKirby Are you about 0=arcsin(0)?

@DavidKirby right C:

@DavidKirby it's something not traditional, right?

Still can't get it

@DavidKirby Thanks, let me think.

@DavidKirby So I should do something with zero...

hi

What approach should I use to compute this equation? arcsinx+(x-1)/(sqrt(1-x*x))=0. I need only hint, not solution, please.

Hello everyone

Bye

Alright, thanks!

@MattN. yep, I know how to answer with example, just wondering should I give general answer or with example...

@MattN. so I have to provide any example? There is no general answer?

Could please somebody explain question? What are the similarities and differences between a function existing at a point and a limit of a function approaching a point? Really can't get it.

Hello everyone
