b) Spherical Helix Points
c) Intersection Coordinates
d) Helical Sphere Overlaps

Answer 1

Finding where a helix intersects a sphere involves substituting the parametric equations of the helix into the equation of the sphere and solving for the parameter, which leads to the intersection coordinates.

Step-by-step explanation:

The task of finding at what points a helix intersects a sphere involves solving a set of equations that represent each geometric object, typically in a Cartesian coordinate system. A helix can be parametrically represented by equations such as x = a × cos(t), y = a × sin(t), z = b × t, where t is the parameter, and a and b are constants that define the helix's dimensions. The equation of a sphere with radius R centered at the origin is
`x^2 + y^2 + z^2 = R^2.`

To find the intersection points, you need to substitute the helix equations into the sphere's equation and solve for t. This may result in one or more values of t, which correspond to the intersection coordinates. You then substitute these t-values back into the helix equations to get the Cartesian coordinates of the intersection points.

The solution requires knowledge of multivariable calculus and algebra, and it may involve techniques such as factoring, using the quadratic formula, or numerical methods if the equations do not simplify neatly. The precise number of intersection points will depend on the specific values of a, b, and R.
