Trig

This is when you would use tan^-1

Or tangent inverse

You’re trying to find x

And you know the value of tan x

[coarse tapir]

so if im finding x i use tan-1 but if im finding a length like Hypo then I use tan ?

[vast burrow]

Uh for hypo you’d usually use sin or cos or if you have both sides except the hypo just Pythagoras theorem

[coarse tapir]

so how would I know when to use tan / cos / hyp -1 ?

vise versa

[vast burrow]

Basically $\tan^{-1}(\tan x)=x$ for $-90<x<90$

Where x is in deg

Muus

[vast burrow]

So if you know the value of tan x

[coarse tapir]

sorry still a bit confused why is money involved 🤣

[vast burrow]

You use tangent inverse to find x

ok thanks
