r=4/ 2-2 cos theta

check_circle

Step 1

Given:

Step 2

Calculation: help_outlineImage TranscriptioncloseTo graph the polar equation, we have to find the type of conic ер ...) The formula to find the conic type is r 1tecos Where e is the eccentricity and p| is the distance between the focus and the directrix If e 1, the conic is ellipse e 1, the conic is parabola e 1, the conic is hyperbola fullscreen
Step 3 help_outlineImage TranscriptioncloseThe polar equation can be written as 4 r = 2-2cos 4 r = 21-cos) 2 (2) 1-cos 0 Comparing (1) and (2), we get e =1 p =2 The value of e is 1, from this we concluded that the conic type is parabola fullscreen
