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

Change θ=α, whereα is a constant, to the rectangular system

Short Answer

Expert verified

The given equation in rectangular system isxsinα-ycosα=0

Step by step solution

01

Step 1:Given information

The given expression isθ=α

02

Step 2:Simplification

Converting the equation θ=αin the recatangular system as below

Since tanθ=yx

⇒θ=tan-1yx

Now,

substituting in θ=α

tan-1yx=α

⇒yx=tanα

⇒yx=sinαcosα

⇒xsinα-ycosα=0

Therefore, the given expression in rectangular system isxsinα-ycosα=0
