Definition of a radian s= |
s = rθ |
|
|
In the unit circle since r=1 then s= |
s=θ |
|

unit circle |
draw it |

|
starting angle of tan |
set parenthesis = - π/2 |

|
Sin & Cos graph y= |
y= d + a sin (bx - c) d: vert. shift a: amplitude b: Period = 2π/b c: c/b (Start angle -> set parentesis to 0 unless its tan set to -π/2) |
|
|
Tan & Cot graph |
y= d + a tan (bx - c) d: vert. shift a: amplitude b: Period = π/b c: c/b (Start angle -> set parentesis to -π/2) |

squared = |
= +_ radican |
|
|
solve: cos^2 x +cos x = 1 |
move one over and factor (Remember: It's just algebra, you can substitute a variable for each function) 1. Factor 2. add fractions 3. square binomials 4. create monomial denominators *use identities when possible *If none of the above work, concert to sin and cos |
|
|
solve: cos x + 1 = sin x |
square both sides then check each solution in the original equation |
