A) =IF(E3(C3-E3) /(D3-B3) ,D3-SQRT((D3-B3) *(D3-C3) *(1-E3) ) ,B3+SQRT((D3-E3) *(C3-B3) *E3) )
B) =IF(E3(D3-B3) /(C3-E3) ,B3+SQRT((D3-E3) *(C3-B3) *E3) ,D3-SQRT((D3-B3) *(D3-C3) *(1-E3) ) )
C) =IF(E3(C3-E3) /(D3-B3) ,B3-SQRT((D3-E3) *(C3-B3) *E3) ,D3+SQRT((D3-B3) *(D3-C3) *(1-E3) ) )
D) =PsiTriangular(B3,C3,D3)
