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.
Step-by-step explanation:
Answer:
(5.83, 2.11, 2)
Step-by-step explanation:
To convert from rectangular coordinates to cylindrical coordinates we use
Therefore (-3,5,2):
So the coordinates are (5.83, 2.11, 2)
