Find the radius and the center of this circle. Just compare (x - 2)2 + (y + 3)2 = 42 with (x - h)2 + (y - k)2 = r2 It might not be difficult to see immediately that r = 4. However, to find h and k, we can solve the two equations x - h = x - 2 and y - ...
to find the Taylor series of {eq}f(x)=\sin(9x) {/eq} at {eq}c=0 {/eq}. Then find the radius of convergence of this power series. Taylor Series: Suppose that {eq}f {/eq} is a smooth (that is, infi...
Show that the equation represents a circle and find the centre and radius. {eq}x^2+y^2+x=0 {/eq} Circle The circle is a geometric shape that has all its points at a constant distance from a point. Specifying this point (center of the circle) and the constant ...
Engineers should calculate the radius value of this circle to curve the composite sheets precisely the same as a circle using an engineering machine and frontage of the convex or concave parts of buildings. Engineers use a formula to find the radius of the circle in similar cases of frontage ...
Answer to: Consider the equation of the sphere: x^2 + y^2 + z^2 - 8x + 4y = 16. A) Find the radius of the sphere. B) Find the center of the sphere...
