1. The problem statement, all variables and given/known data: r vector = 3t i + (4t-5t2)j. Find the angle made by the vector with respect to the x-axis and the y-axis. 2. Relevant equations: A.B=AxBx+AyBy 3. The attempt at a solution: I tried to take the dot product of the unit vector along x-axis and r. I did the same for the y-axis but did not get anything useful.
