(Note that a formula for true thickness can be derived using basic trig in emergencies!)
I would strongly recommend deriving the formula yourself, so you understand how it works. There are several standard formulas for true thickness that cover various situations.
Do you think you could post those formulas here? I'm having a hard time grappling more complex true thickness problems that don't just use the basic formula. thanks
yeah, i'm not gonna lie, i asked that question before TSTs when i didn't know that much about the event. my accuracy improved a lot when i started drawing stuff out then applying trig as opposed to formulas--i'm not very good at identifying which formula applies to which situation yet, but drawing a picture really, really helps imo
that being said, i found T = w*sin(D - S)
where D = dip, S = slope, T = true thickness on one practice test. hope that's helpful
