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

. Change ϕ=π2to 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 ϕ=π2into rectangular system.

Here,width="49">ϕ=π2

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 ϕ=π2into cylindrical system.

Substituting ϕ=tan-1r2in the equation ϕ=π2

So ϕ=π2

width="114">tan-1rz=π2

width="97">rz=tanπ2

localid="1653034873552" rz=10

z=0

Hence,The equation in cylindrical coordinates z=0
