To find the rectangular coordinates given the polar coordinates (3, π/2), where 3 is the radius and π/2 is the angle in radians:

The rectangular coordinates (x, y) can be found using the formulas: x = r * cos(θ) y = r * sin(θ)

Substitute the given values: r = 3 θ = π/2

x = 3 * cos(π/2) = 0 y = 3 * sin(π/2) = 3

Therefore, the rectangular coordinates given the polar coordinates (3, π/2) are (0, 3).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
