Great, thank you!
Also, how do you interpret the "find the (x,y) coordinates of the corresponding points"? What do you reckon it's asking for? Just to plug in the different t values into each x and y equation initially given?
Would it mean that the bird was either stationary or floating in place?
Ah, that means I need to include every interval of pi/2 up until 8pi/2 correct?
The flight of a bird follows the curve x=t-cos(t), y=3-2sin(t)... where 0<=t<=4pi is the time in seconds.
a) What times is the bird flying horizontally? find the (x,y) coordinates of the corresponding points.
b) What times is the bird flying vertically? find the (x,y) coordinates of the...
There are two railroads, represented by the curves y=(1/2)x2+7, and x2+y2=1. I am supposed to find a straight line connection so that a atrain can get from one curve to the other.
I have drawn a simple diagram to help me picture things:
