- 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
- a^2= b^2+c^2-2bcCosA
- area of sector
- radian measure
- radians to degrees
- radians x 180/pi
- degrees to radians
- degrees x pi/180
- radians to degrees
- degrees
- theta/360 x pi r^2
- radians
- theta/ 2pi x pi r^2
- radian measure
- Arc length
- degrees
- theta/360 x 2 pi r
- radians
- theta/ 2 pi x 2 pi r
- degrees
- area of segment
- area of sector- area of triangle
- no rounding till end
- this is when the mode matters
- area of sector- area of triangle
- area of triangle= 1/2absinC
