SOHCAHTOA
sinθ = opp / hyp
cosθ = adj / hyp
tanθ = opp / adj
FIND ANGLE
θ = sin⁻¹(opp/hyp)
θ = cos⁻¹(adj/hyp)
θ = tan⁻¹(opp/adj)
EXAMPLES
opp=3 hyp=5 → θ≈36.87°
adj=4 hyp=5 → θ≈36.87°
FIND SIDE
opp = hyp·sinθ
adj = hyp·cosθ
opp = adj·tanθ
VALID INPUTS
Sides must be positive
Angles in degrees (0–89.9)
For sin/cos: ratio must be 0–1
