Hey guys,

I was wondering if anyone had the full solutions to this book: Longman 2U mathematics Book 1 S.B Jones and K.E. Couchman (This is for Preliminary 2U Maths btw), or specifically solutions for pg 158 and pg 159 (teacher photocopied a sheet and it didnt show exercise).











thanks in advance,
lookoutastroboy

hey steve, ty for replying, oh yeah the two pages did not show any of the exercise numbers but pg 159 had the heading "THE EXACT TRIGONOMETRIC RATIOS OF 30 DEGREES, 45 DEGREES AND 60 DEGREES).










thanks again,
