@Mariusz Iwaniuk
How to use your code with
sin(9*x-(1/3)*Pi) = sin(5*x-(1/6)*Pi)?

## I agree with you...

@nm Yes, k is an Integer. I agree with you.

## Thank you vey much...

@tomleslie Thank you vey much.

## Thank you very much...

@tomleslie Thank you very much. A small question. Why I get error when I use nops(evalf(sol)) ?

## How can I get the exact of the numbers a...

@Carl Love How can I get the exact of the numbers a, b, c?
By hand, I can prove that, the line Delta passing the point DD and perpendicular to the plane (ABC). And then,

maxS = Distance(A, DD)+Distance(B, DD)+Distance(C, DD);

My code get

[9.37769297305868754, [a = .801783725149603, b = .534522484467394, c = .267261242390448]]

## Thank you very much....

@Joe Riel Thank you very much.

## @mmcdara Because I choose polynomia...

@mmcdara Because I choose polynomial degree 10, then when tends to plus or minus infinity, f(x) always tend to infinity. It didn't fit with figure.
I think, we need to choose a function that is suitable for the drawing.

@tomleslie I like your answer. It closes with my picture. I copied your code to LaTeX and used piecewise. It looks good (except that the dots are maybe not exactly at the positions of the local extrema). Can you repair positions of the local extrema?

## When x tends towards +infinity?...

@mmcdara With the given figure, When x  tends towards  +infinity, then f(x) tends towards  +infinity, too?

## Thank you very much. May be positions of...

@tomleslie Thank you very much.

## Thank you very much....

@vv Thank you very much.

## How about real in command?...

@vv How about real in command? limit(sqrt(x^2-3*x+2), x = 2, real)

## Can you post your code?...

@vv Can you post your code?

## arrow on each axis...

@acer How can I get the arrow of each axis (ox and oy)? For exmaple

## @vv How about ^+ in the line? sol...

@vv How about ^+ in the line?

`solve( (P-H)^+ . (B-A), t ):`
