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.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
