A satellite travels in a circular orbit of radius R. If its x-coordinate decreases at the rate of 2 units/s at the point (a, b ) how fast is the y-coordinate changing?

An object is moving in the clockwise direction around the unit circle x^(2)+y^(2)=1 . As it passes through the point (1/2,(sqrt(3))/2) , its y-coordinate is decreasing at the rate of 3 unit per second. The rate at which the x-coordinate changes at this point is (in unit per second)

An object is moving in the clockwise direction around the unit circle x^(2)+y^(2)=1. As it passes through the point ((1)/(2),(sqrt(3))/(2)), its y- coordinate is decreasing at the rate of 3units per second.The rate at which the x-coordinate changes at this point is.

A point is moving on y = 4 - 2x^(2) . The x-coordinate of the point is decreasint at the rate of 5 units/sec. Then the rate at which y - coordinate of the point is changing when the point is at (1,2) is
