For the above graph that can be described as y k in this ca

For the above graph that can be described as y = k in this case let\'s call it y = -4 Convert this to a polx equation Solve for r and enter the right side of the equation Use one-line notation When you need theta jest write out the word theta Put parenthesis around function arguments For example cos(theta) For the above graph of of the polar equation theta - k Find k and the exact rectangular equation solve for y and just give the right side of the equation Use the class standard for one line notation at the beaming of the

Solution

For polar coordinates,

r = sqrt(x^2 + y^2)

Here x = 0, y = -4

Then r = sqrt( 0 + 16) = 4
