R = sec(θ) − 2cos(θ), where -π/2 < θ < π/2
Alex

Answer:

  y = (x/(1-x))√(1-x²)

Step-by-step explanation:

The equation can be translated to rectangular coordinates by using the relationships between polar and rectangular coordinates:

  x = r·cos(θ)

  y = r·sin(θ)

  x² +y² = r²

__

  r = sec(θ) -2cos(θ)

  r·cos(θ) = 1 -2cos(θ)² . . . . . . . . multiply by cos(θ)

  r²·r·cos(θ) = r² -2r²·cos(θ)² . . . multiply by r²

  (x² +y²)x = x² +y² -2x² . . . . . . . substitute rectangular relations

  x²(x +1) = y²(1 -x) . . . . . . . . . . . subtract xy²-x², factor

  y² = x²(1 +x)/(1 -x) = x²(1 -x²)/(1 -x)² . . . . multiply by (1-x)/(1-x)

  \boxed{y=\dfrac{x\sqrt{1-x^2}}{1-x}}

__

The attached graph shows the equivalence of the polar and rectangular forms.

PLEASE HELP ME UNDERSTAND! I don’t know how to find.... ML , CD, AC, UW (one explanation is ok too)
nlexa [21]

Step-by-step explanation:

So the way you do this is if it says 'Find AC' and on the angle you see different letters connect then on the lines and name the angle

More that 90°= Obtuse

90° angle= 90° angle

Less than a 90° angle= isosolines angle

The logarithmic expression ln(√e/y^3) can be rewritten as
kvv77 [185]

Answer:

\dfrac{1 - 6 \ln y}{2}

Step-by-step explanation:

\ln \dfrac{\sqrt{e}}{y^3} =

= \ln \dfrac{e^\frac{1}{2}}{y^3}

= \ln e^\frac{1}{2} - \ln y^3

= \dfrac{1}{2} \ln e - 3 \ln y

= \dfrac{1}{2} - 3 \ln y

= \dfrac{1 - 6 \ln y}{2}
