For Capacitance would the S not be S-2 since S/S*3 correct me if I am wrong.

That's what I thought but its s^{-3} in the denominator, its just hard to see what the wrote.

Yep, it's s(-3) in the denominator, therefore s/s(-3) gives us s^4. Hope this helps!

My criticism would be to use different colours to break it up visually for people I'am a artist learning maths lol just noticed a lot of videos do need better presentation to suit all learners.

Just started this so please bear w me. For resistance, I've never learnt a formula that says a volt could become kgm^2A^-1. Am I supposed to just memorise some of these?

no need to memorise, you can usually derive it : )

If I used stefans law for luminosity, is it equivalent to say the base units are m^2 K^4 ?

No, because stefan's constant also has units which you need to take into account. This will be in your data booklet most likely.

Stefan's constant has units Wm^-2K^-4, which cancel out the others and you'd get the S.I base units of W left.

What are units such as Joule and Coulomb called then? Are they known as derived units as well

yes. They are derived, not base units. They are standard units though or SI units. Hope this helps!

depends on the question, but only x=acos(wt) and x=asin(wt) are in radians. The rest only if the question gives you values in radians or you have to find the arclength using s=rtheta
