Find the coordinates of the point on a circle with radius 4 at an angle of 2pi/3 {Please help!!}

The coordinates of the point on a circle with radius 4 at an angle of radians are x = -2 and y = 3.464.

Step-by-step explanation:

This problem ask us to determine the rectangular coordinates from polar coordinates. The polar coordinates of the point in rectangular form is expressed by the following expression:

Where and are the radius of the circle and the angle of inclination of the point with respect to horizontal, measured in radians. If and , the coordinates of the point are:

The coordinates of the point on a circle with radius 4 at an angle of radians are x = -2 and y = 3.464.

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
