SOH CAH TOA broEvery single time we did trig in Math I would always confuse sin and cos for some reason- it always stuffed me until right before my exam where i nearly ran out of time cause i kept on double checking all my triangles-
another neat way to remember it is like
if you consider the unit circle,
sin(x) represents the y value, cosx represents the x value and tanx represents the slope of the line
cotx is just 1/tanx, cosecx = 1/sinx {confusing innit}, secx = 1/cosx
