How are polar and rectangular planes related?

nlexa [21]

Polar coordinates (r,ϑ) and Cartesian coordinates (x,y) are related as follows:

Cartesian -> Polar
x = r cos(ϑ)
y = r sin(ϑ)

Polar -> Cartesian
r^2 = x^2 + y^2
ϑ = arctan( y/x)

The polar coo's can be extended to cylindrical by introduction a dimension z - which is perpendicular to the polar plane, it follows that:

z = z
in between the systems (r,ϑ,z) and (x,y,z)

The polar coordinates are particularly useful when a problem has circular or cylindrical symmetry, i.e. it is usually "easier" to perform calculations on a circle (for example) using the polar coordinates.

Help me with inverse table and start x with -2. Show work please

ANTONII [103]

Answer:

The answer to your question is below

Step-by-step explanation:

Function f(x) = (2 - x)²

Inverse y = (2 - x)²

x = (2 - y)²

$\sqrt{x} = 2 - y$

y = $2 - \sqrt{x}$

$f^{-1}(x) = 2 - \sqrt{x}$

Function Inverse

x f(x) x $f^{-1}( x)$
