3. 3.

   What is the main goal of numerical solutions in IK?

   • To find exact solutions
   • To solve complex non-linear equations
   • To eliminate the use of robotics

   Hint

   Focus on what happens with complex systems.

4. 4.

   True or False: The Gradient Descent Method always converges faster than the Newton-Raphson Method.

   • True
   • False

   Hint

   Think about the efficiency of each method.

5. 5.

   A robotic arm needs to reach a specific point in a cluttered environment. Describe the steps using Damped Least Squares to find a solution, considering the obstacles.

   Hint

   Think about balance between speed and stability.

6. 6.

   Given an initial position and joint angles, apply the Gradient Descent method to minimize the movement of a robotic arm. Describe the mathematical process involved.

   Hint

   Remember the cost function and its minimization process.
