  • Application + Trig
    • area of triangle= 1/2absinC
      • Two angles must be next to each other with angle in middle
    • Sine rule
      • side- small letters on top
      • two sides with corresponding angle
      • angle-  big  Sin letters on top
      • sin A/a= Sin B/b= Sin C/c
    • Cosine
      • a^2= b^2+c^2-2bcCosA
        • two sides and an angle
      • angle-  Cos A= b^2+c^2-a^2/2bc
        • where b and side are next to the angle and a is the one opposite the angle
        • three sides
    • area of sector
      • radian measure
        • radians to degrees
          • radians x 180/pi
        • degrees to radians
          • degrees x pi/180
      • degrees
        • theta/360 x  pi r^2
      • radians
        • theta/ 2pi x pi r^2
    • Arc length
      • degrees
        • theta/360 x 2 pi r
      • radians
        • theta/ 2 pi x 2 pi r
    • area of segment
      • area of sector- area of triangle
        • no rounding till end
        • this is when the mode matters
