Although I guess we should use \(\mu_s\) for static friction.

Wait... I did that wrong. I looked at everything all wrong... It's been a long day!

Dang!

Haha, I'm about to take another look, sorry.

No problem. What you have done, I already consider great ;)

Haha, it's wrong, don't look at it too long! :)

Okay, I am half-way through.

do we mean*

OHHH

ok, I reread the whooole post.

I think I am starting to understand.

(I reread thrice.)

So, let me sum up to see if I got this clear.

Out of curiosity, how would I find the optimal angle?

That sounds good!
Optimal angle... Time for the thinking cap.

So, a formula for the optimal angle as a function of \(\mu_s\)...

By the way, if you dont mind me asking, what is your background? You're good at this.

I've had lots of time to practice :)

ohhh ok. ;) that's why

Haha, yep!

Oh of course! It finds the minimal value!

All those cal courses now come back to me!

Haha, glad they came back to you!

I don't know how to make it help at the moment, though!

Finding the angle....

Hmm...

I might be wrong though!

It's weird that we didn't have to find whether it was a minimum or maximum, though.
