Write true or false for each statement. 1. The polar equation r = 6sin(theta) for 0 is less than or equal to t which is less than or equal to 2pi is tracing a circle symmetric to the x-axis. 2. The polar equation r = 4cos(theta) + 6sin(theta) for 0 is less than or equal to t which is less than or equal to 2pi is tracing a circle centered at the point (2,3). 3. The polar equation r = 1 / 2cos(theta) + 4sin(theta) for 0 is less than or equal to t which is less than or equal to 2pi is tracing an ellipse
