3. Complex Numbers

4. Rectangular form : Any complex number z can be uniquely represented as a point in the x-y plane, where the x-coordinate is Re z and the y-coordinate is Im z. - You can think of i as a unit vector in the maginary" (y) direction. - The magnitude of z is just the length of the vector from the origin. Polar form : We can also write z in polar form as:

5. Arithmetic

7. A complex number z lies on the curve |z+6| =3. The largest magnitude of |z+3| will be: a. 6 b. 3 c. 36 d. 12

11. Determinants & Matrices det = a det - b det + c det = aei + bfg + cdh - afh - bdi - ceg = a ( ei - fh ) - b ( di - fg ) + c ( dh - eg )

12. Sampler

14. First find the cofactor of each element. Solution: Find the adjoint of the following matrix: Example:

15. As a result the cofactor matrix of A is Finally the adjoint of A is the transpose of the cofactor matrix:

16. C - Cofactor Inverse of a matrix
