### Key Equations

 Sinusoidal functions $f( x )=Asin( Bx−C )+D f( x )=Acos( Bx−C )+D f( x )=Asin( Bx−C )+D f( x )=Acos( Bx−C )+D$
 Shifted, compressed, and/or stretched tangent function $y=Atan( Bx−C )+D y=Atan( Bx−C )+D$ Shifted, compressed, and/or stretched secant function $y=Asec( Bx−C )+D y=Asec( Bx−C )+D$ Shifted, compressed, and/or stretched cosecant function $y=Acsc( Bx−C )+D y=Acsc( Bx−C )+D$ Shifted, compressed, and/or stretched cotangent function $y=Acot( Bx−C )+D y=Acot( Bx−C )+D$
