1.3

Convert the answers in (1.2) in polar and exponential form of complex numbers.

1.4

Use de Moivre’s Theorem to determine the three cubic roots of one expresiing the answers in both polar and Cartesian form.

1.5

Find a formula for sin (3θ) in terms of cos (θ) and sin (θ) using de Moivre’s theorem.

LO2 Solve systems of linear equations relevant to engineering applications using matrix methods

Task 2.0

2.1 determine the determinant of 3x3 matrix :

2.1  a d.c circuit comprises three closed loops. Applying kirchhoff’’s laws to the closed loops gives the following equations for current flow in mA.:

2x+3y -4 z=26 x - 5y -3z =-87

-7x+2y+6z =12

2.21  represent the above linear vector equations in matrix form and use Gaussian elimination to find the currents x,y& z .

2.22  solve the system using the inverse matrix method.

2.23  Validate the matrix solutions using computer software.
