sin-1(T) opp/hyp

sin-1(T) 4/6

Angle = 41.81 Degrees

Turret Hacked!!

As normal, I was confused on this video

For me solving the issue seemed like this:
How far does the player have to move to not be shot by the cannon
I would take a horizontal line from the player hitbox and then move that line across until it interests the 25*d line, that is the safe zone under the ‘‘enemy’’

My Calc shows sin, sin-1 and sinhsinh
does this mean asin? I’m assuming so

Hi there,

asin returns the arcsinus so the inverse. This is the same as sin^{-1} or sin-1 on your calculator.
sinh is a hyperbolic function, this is not the same as the inverse.

Kind regards, Lisa

After inadvertently using the incorrect function, I backtracked and got the right answer. I’ll get the pneumonic down eventually - in the meantime here’s my answer:

Θ = asin(4/6)
Θ = asin(2/3)
Θ = 41.81 degrees

The above is less than our maximum 45 degree limit, so we should be able to hack the scanner.

At first I used tan/atan because I forgot that the hyp is always that, even if it’s adjacent to the angle we want. Doh! We need the the angle associated with sin (y axis).

So using sin = opp/hyp => sin(a) = 4/6 => sin(a) = 2/3

We are looking for the angle, so we need to use the Inverse Functions.

asin(2/3) = 41.81

This is a smaller angle than 45 so yes, we can hack this turret!
