For the following curves, (a) eliminate the parameter to give a Cartesian equation for the curve Sketch the parametric curve with an appropriate direction arrow if possible Give parametric equation, including an appropriate parameter interval, for a circle of radius three centered at (2, -5) traversed Twice in the counterclockwise direction Three times in the clockwise direction Sketch the following polar curves. Justify your sketch with a table of points or an appropriate Cartesian graph

Explanation / Answer

7)r=- theta is a straight line through origin and slope -1 8)just extend the cos theta by stretch 2 and shift it by 1 9)just extend the sin theta by stretch 2 and shift it by 1 upwards 10) just extend the sin theta by stretch 2 and shift it by 1 downwards now reflect along X axis 11)sfift sin theta by pi/4 in positive direction of x and shift in the vertical direction by 2 unit I think now your doubts are clear rate this
