Because "circular-type" functions can be more easily described by the periodic functions 
and 
, which are deeply involved in the behavior of "circular-type" functions. Also, using a polar coordinate plane allows you to draw graphs of equations that typically aren't functions.
For example, the unit circle requires two equations to be graphed to fully represent the circle in the rectangular coordinate plane.
On the other hand, in polar coordinates, substituting
and 
reduces this to a constant function,
(since by definition, 
)

Answer:
Step-by-step explanation:
Give the expression ax – c = bx + d, we are isolate x i.e we are to make x the subject of the formula.
ax – c = bx + d
Step 1: subtract bx from both sides
ax – c = bx + d
ax-bx = d+c
Step 2: Factor out x in the left hand side of the resulting expression
x(a-b) = d+c
Step 3: Divide both sides by the coefficient of i.e (a-b)
Hence Victoria can justify the step 3 of her work by dividing both sides of the expression in 2 by a-b
