Hi guys,
I completed my HSC in 2010. I am keen and willing to offer tutoring to anyone interested. I scored an ATAR of 99.80, 3u HSC mark of 99 and 4u mark of 97.
$20/hour.
I live in the Western Sydney region so tutoring will be held at Parramatta library, Auburn library, Merrylands library...
tan(x).sin(x) = 3sin(x) - sec(x)
sinx/cosx . sinx = 3sinx - 1/cosx
sin^2 x /cosx = 3sinx - 1/cosx
sin^2 x = 3sinx cos x - 1
sin^2 x - 3 sinx cosx + 1 = 0
sin^2 x - 3 sinx cos x + cos^2 x + sin^2 x = 0
2sin^2 x - 3sinx cosx + cos^2 x = 0
(2sin x - cosx) (sinx - cos x) = 0
continue on yourself...
