this is what im working on rn
08:44
but the main thing that confuses me is what do i use. Cos, sin or tan

heinrich5991 2021-12-07 08:44:23Z
are you allowed to use a calculator that can do arcsin etc.?
Avatar
Cracker Barrel 2021-12-07 08:44:40Z
we use desmos so yeah we can

heinrich5991 2021-12-07 08:45:20Z
I think the main insight is that you need to use one of arcsin, arccos or arctan if you want to go from a length ratio to an angle
08:45
can you tell me the definition of one of sin, cos, tan?

i have it in my notes one sec

sin = opposite over hypotenuse
Avatar
heinrich5991 2021-12-07 08:47:04Z
so sin(x) = opposite / hypotenuse
08:47
or the other way around x = arcsin(opposite / hypotenuse)
08:47
what's opposite and what's hypotenus in our case?
Avatar
Cracker Barrel 2021-12-07 08:47:58Z
the opposite would be 14 and hypotenuse would be 48
08:48
no
08:48
wair
08:48
wait
08:48
hypotenuse would be 50
Avatar
heinrich5991 2021-12-07 08:48:27Z
yes
08:48
so how do you calculate the angle x?
Avatar
Cracker Barrel 2021-12-07 08:49:39Z
sin(x) (14/50)
Avatar
heinrich5991 2021-12-07 08:49:50Z
sin(x) = 14/50, yes
08:50
arcsin is the inverse of sin
08:50
so you can turn that into x = arcsin(14/50)
