Answer:
Since r is the distance from the origin to (x,y), it is the magnitude r=√x2+y2. Alternatively, from the equation (1), one can calculate directly that x2+y2=r2cos2θ+r2sin2θ=r2(cos2θ+sin2θ)=r2.

Answer:
n^2+2n+1
Step-by-step explanation:
-2-8-18-32-50
difference=-6-10-14-18
common differences=-4-4-4-4-4
-2-8-18-32-50
n^2=1,4,9,16,25
minus it
=-1,-4,-9,-16,-25
differences 2,5,7,9
common differences=2
2,4,6,8
so 2n+1
so the answer is n^2+2n+1
Answer:
(-8, -4), (-2, 6), (0, 0), (2, 10), (5, 0)
Step-by-step explanation:
A critical point is a point where the slope is zero or undefined. On this graph, every marked point except (-5, 0) is a critical point.
__
<em>Additional comment</em>
Critical points will be found at local extreme values, places where the tangent is vertical, and places where the slope has a discontinuity (such as (2, 10) and possibly (5, 0)).
