I see you guys/girls seem to complain way too much over maths, so i have decided to make a thread similar to "4unit revising game" but this one will consist of questions that will test you knowledge on "maths"...
So here it comes
question 1) Consider the quadratic equation
x^2-(2cos@)x+1 =0
which has roots alpha and beta...
find an expression for alpha and beta and hence prove that alpha^10 + beta^10 = 2cos(10@)
it will be a good practice for your trails + hsc xD
