So thot I would jump off the diving board into the world of SAGE
However...OK Im in a lock down here with my Governor ordering us stay hometho

So thot I would jump off the diving board into the world of SAGE

However when I went to google for guiding light on this I got intimidated fast

So Does anyone done square one and more I would like some tips

I did some SAGE about a year ago but it was a University Lab with a lot of help
I have forgotten everything...

thanks ahead....

I do know that SAGE is collaborative with Latex so that is a big plus

I am looking the following:

Describe and draw with Geogebra the region where the following functions are continuous:

$f(x,y)=\ln (x-3y)$

$f(x,y)=\cos^{-1}(xy)$

Do we have to find the region manually or is it possible to find it also using Geogebra? (Wondering)

I am looking at the following:

1. We have the function $f(x,y)=y-x^2-1$. Write the appropriate commands in Geogebra that draw a contour line with $f(x,y)=\frac{3709}{2000}$.

Could you give me a hint what command we have to use here? Do we just plot $y-x^2-1=\frac{1374}{2000}$ ? (Wondering)

2. Give the graph of the below functions in Geogebra and find the countour lines $f(x,y)=c$ where $c$ is in the interval $[0,10]$ and each contour line has to have distance from the next one $0.4$.

Do we use for that the command "Sequence(\cos (xy)=c, c, 0, 10)" ? (Wondering)
