Question

What would be the Cartesian point?

The polar coordinate is given by \((r, \theta) = \left(4, -3 + 2\pi\right)\) with \(r > 0\).

This expression represents a point in polar coordinates, where \(r\) is the radial distance from the origin, and \(\theta\) is the angular coordinate. The angle \(-3 + 2\pi\) demonstrates an adjustment in the angle measure, and due to the addition of \(2\pi\), it's equivalent to rotating by \(360^\circ\), which can help in finding a positive equivalent angle. 

The radial distance \(r\) is positive, indicating the point lies on the same radial line as \((4, -3)\), but adjusted to fit the standard form by adding \(2\pi\). 

The green check mark indicates that these coordinates satisfy the condition \(r > 0\).
