Describe the graphs of the equations and provide alternative equations in the specified coordinate systems.

. Change Ï•=Ï€2to the rectangular and cylindrical systems.

Short Answer

Expert verified

The equation in rectangular coordinatesz=0

The equation in cylindrical coordinatesz=0

Step by step solution

01

Step 1:Given information

The given expression isϕ=π2

02

Simplification 

The objective is to convert the equation Ï•=Ï€2into rectangular system.

Here,width="49">Ï•=Ï€2

width="217">⇒cos-1zx2+y2+z2=π2

width="200">⇒zx2+y2+z2=cosπ2

localid="1653033836537" ⇒zx2+y2+z2=0

⇒z=0

Hence, The given equation in rectangular coordinates is z=0

Now,

To convert to the equation Ï•=Ï€2into cylindrical system.

Substituting Ï•=tan-1r2in the equation Ï•=Ï€2

So Ï•=Ï€2

width="114">⇒tan-1rz=π2

width="97">⇒rz=tanπ2

localid="1653034873552" ⇒rz=10

⇒z=0

Hence,The equation in cylindrical coordinates z=0
