Algebraic Techniques – Solutions

The following solutions are now available for download from the Wiki.

Ex 1.1 Algebra of polynomials (Complete solutions)
Ex 1.2 Systems of simultaneous_linear_equations (Incomplete solutions)
Ex 1.3 Algebra of exponential and logarithmic functions (Complete solutions)
Ex 1.4 Algebra of polynomials (incomplete solutions)

For 1.2 you need to understand how to use your TI89 to solve simultaneous equations, particaulrly three unknowns with three equations. For this you use the SIMULT or RREF functions. Video tutorials on how to do this can be found at:

Step by step guides on:

1. How to use a TI89 to solve simultaneous equations with 3 unknowns.

2. Using the TI89 rref function to solve simultaneous equations.

3. Using the TI89 simult function to solve simultaneous equations.

4. Using the TI89 to find the intersection of two lines.

Also the incomplete solutions to Ex 10.1 have been posted.
