+the fist lesson was not a nice time
+started with setting up techy stuff, the classroom, outlook
+then got straight in with a test
+
+the test wasnt too bad but everyone else was alot faster, work on speed
+cosine rule killed me as well as a large similtanius equation
+work on them
+
+need to chase up teacher on the text book login but have already sent an email so not too worried
+
+the people next to you seem nice, although quiet as expected

+maths was fine 
+
+just did stuff from the work book (exersise 1d)
+
+worked on ^x

+todo:
+ learn the 7 rules of them

+3rd maths lesson, going well so far, we are working on factorizing in the first half
+
+i think we will be doing surds in the second half
+
+the fatorizing is pretty easy overall
+
+for factorizing things like 4x^2 + 4x + 3, you multiply the first value and the last then find a pair of numbers that adds together to equal the middle value, then put them back in individually and factorise the thing
+
+surds does not sound fun
+
+surds arent that bad really, to simplify them split them into 2 factors, one must be a square number
+then square root the square number and move it out of the sign, then leave the remaining value
+
+the lesson was fun, everyone was somewhat interested in the thinkpad, ill have to show them more next lesson
+the guy oposite you knows what linux is
+
+nothing was overly chalenging

+so far so good with maths, todays work was quite hard however
+
+had to work on some completing the square
+
+also found out how to solve some weird quadratics
+
+if something is like x^6+x^3+2 its still a quadratic
+to solve it you would say let y = x^3
+then rewrite the equation as y^2+y+2
+then solve with the quadratic formula or factorizing
+and then cube root the ans to give it in terms of x for the final anwser
+
+you can only do that when all the powers line up with something that can be divided to match a quadratic
+so x + x^7 + 23 wouldnt work

+writing this late and cant really remember what we did
+we did some work on completing the square which is never too hard, however i should try and do some more work on it
+try and remember how to put something into a completed square form as well as take it out
+
+x^2 + 6x + 6
+(x + 3)^2 - 3
+method is to half B, then subtract b^2, and add whatever is needed to make sure + c works
+
+this can be used to find the turning point of the graph, the section in brackets needs to have its sign flipped
+this is similar to using factorising to solve a quadratic
+the value outside the bracket stays as is
+in the example given the turning point would be (-3, -3)
