class TrigonometricFunctionRoots from math
|
|
|
|
---Purpose: This class implements the solutions of the equation
|
|
-- a*Cos(x)*Cos(x) + 2*b*Cos(x)*Sin(x) + c*Cos(x) + d*Sin(x) + e
|
|
-- The degree of this equation can be 4, 3 or 2.
|
|
|
|
|
|
uses Array1OfReal from TColStd,
|
|
OStream from Standard
|
|
|
|
raises NotDone from StdFail,
|
|
OutOfRange from Standard,

Create(A, B, C, D, E: Real; InfBound, SupBound: Real)
|
|
---Purpose: Given coefficients a, b, c, d , e, this constructor
|
|
-- performs the resolution of the equation above.
|
|
-- The solutions must be contained in [InfBound, SupBound].
|
|
-- InfBound and SupBound can be set by default to 0 and 2*PI.

|
Create(D, E: Real; InfBound, SupBound: Real)
|
|
---Purpose: Given the two coefficients d and e, it performs
|
|
-- the resolution of d*sin(x) + e = 0.
|
|
-- The solutions must be contained in [InfBound, SupBound].
|
|
-- InfBound and SupBound can be set by default to 0 and 2*PI.

Create(C, D, E: Real; InfBound, SupBound: Real)
|
|
---Purpose: Given the three coefficients c, d and e, it performs
|
|
-- the resolution of 2*b*cos(x)*sin(x) + d*sin(x) + e = 0.
|
|
-- The solutions must be contained in [InfBound, SupBound].
|
|
-- InfBound and SupBound can be set by default to 0 and 2*PI.
