x=2
Multiplying length by width equals square footage
The derivative of sqrt(2) is zero.
When it has 4 equal sides and 4 equal right angles of 90 degrees
If ... the square of (the x-coordinate of the point minus the x-coordinate of the center of the circle) added to the square of (the y-coordinate of the point minus the y-coordinate of the center of the circle) is equal to the square of the circle's radius, then the point is on the circle.
The square root of x = x to the power of a half

the derivative is 0. the derivative of a constant is always 0.

The square root of x = x to the power of a half
Square the two smaller ones and see if that total equals the square of the larger one.
y=(8x).5 + (4x).5 = (2+2sqrt(2))x.5 y'=(1 + sqrt(2))/sqrt(x)

The derivative of ANY constant expression - one that doesn't depend on variables - is zero.
The derivative of any constant - any expression that does not involve the independent variable - is zero.
The derivative, with respect to x, is -x/sqrt(1-x2)
