What Engineering Mathematics IV covers

Engineering Mathematics IV covers complex numbers, co-ordinate geometry, loci and Laplace transforms for Biomedical Engineering Level 6. Complex numbers start the unit, with arithmetic operations, polar and exponential forms, and solving equations. Co-ordinate geometry deals with polar and Cartesian equations, graphs of polar equations, and normals and tangents. Loci include the locus in relation to a circle and engineering applications. Laplace transforms close the unit: their properties, inverse transforms of simple functions, and the solution of differential equations and simultaneous differential equations.
