Did you know?
WebIf you have the slope-intercept form y = m x + b, you can substitute y = r sin θ and x = r cos θ to get r sin θ = m ( r cos θ) + b, and then solving for r in terms of θ gives r = b sin θ − m cos θ. More generally, if the line has equation a x + b y = c, you can solve for r in terms of θ to get r = c a cos θ + b sin θ.

WebNov 16, 2024 · Some lines have fairly simple equations in polar coordinates. θ = β θ = β. We can see that this is a line by converting to Cartesian coordinates as follows θ =β tan−1( y x) =β y x =tanβ y … WebThe point (which is on the circle of radius ) is on the radius with a slope of so the tangent line has slope . The equation of is then In polar coordinates, this becomes The negative sign in the numerator of the expression places the tangency in the third quadrant.
WebI get the correct derivation but I don't understand why this derivation is wrong. This is my logic: as the angle becomes 0, R becomes a line. Using the integral, R acts like a windshield wiper and "covers" the area underneath the polar figure. Keep in mind that R is not a constant, since R describes the equation of the radius in terms of θ. Webis polar equation of a circle with radius R and a center at the pole (origin). Example: Convert the polar equation of a circle r = - 4 cos q into Cartesian coordinates. Solution: As, r = - 4 cos q then r2 = - 4 r cos q, and by using …
