Answer» A vetor $\to a$ has components $3 p$ and $1$ with respect to a rectangular cartesian system. This system is rotated through a certain angle about the origin in the counter clockwise sense. If with respect to new system, $\to a$ has components $p + 1$ and $\sqrt{10},$ then a value of $p$ is equal to:
