JUST FINISHED THAT MATH PROJECT FOR BROB AND I CAN'T STAY AWAKE IF MY LIFE DEPENDED ON IT.
Section 10-1
When everyone and their mother went over this section I chose not to, just in case I had no idea what to do a blog on, and what do ya know.
Formulas:
Sin: (alpha +/- beta) = sinAcosB +/- cosAsinB
Cos: (alpha -/+ beta) = cosAcosB +/- sinAsinB
ex. Find the exact value of sin 75
sin45cos30 + cos45sin30
= sqrt(2/2)(1/2) + sqrt(2/2)sqrt(3/2)
= sqrt(6) + sqrt(2)
