So the first week of lectures has ended. In MAM1000 we have only dealt with sets and functions thus far, but in great detail using set builder and interval notation. In our first tutorial we have even started using parametric equations. The Modulus(Absolute value) Function had been added by the end of the week as well. Modulus function is nice to work with as the answer coming out of it must always be positive. If a variable (x) is shown in modulus it must be its non-negative version for example: if x in itself has a negative value then the value of x after modulus has been applied will be -x as this will then be a positive number. Similarly if x is positive then the output will be x. |x| is how modulus is written. We have now also learned that |x+y|<=|x|+|y|, this is called the Triangle inequality and is very important for future use.…
