Start by understanding that polar coordinates are represented as (r, θ), where r is the radius or distance from the origin, and θ is the angle from the positive x-axis.
Given the Cartesian coordinates (1, 1), calculate the radius r using the formula r = \sqrt{x^2 + y^2}. Substitute x = 1 and y = 1 into the formula.
Next, determine the angle θ using the formula θ = \arctan\left(\frac{y}{x}\right). Substitute x = 1 and y = 1 into the formula.
Since both x and y are positive, the point lies in the first quadrant, and the angle θ should be between 0 and \frac{\pi}{2}.
Combine the calculated values of r and θ to express the point in polar coordinates as (r, θ).
