Challenge Problems
Push your limits with challenges.
Question 1
Two vectors \( \vec{a} = [3, 4] \) and \( \vec{b} = [1, 2] \) are given. Calculate the dot product and the angle between them.
💡 Hint: Use the magnitudes of both vectors and the dot product to find the angle.
Question 2
A vector \( \vec{c} \) lies in the xy-plane and makes a 45-degree angle with the x-axis. If its magnitude is 10, represent \( \vec{c} \) in component form.
💡 Hint: Use trigonometric functions to resolve the vector into its components.
