Explain how creating a model provides a practical solution for some scientific research.

A scientific model is a simplified visual representation of the complex system.  

They are used during scientific research:

1. To prove and disprove the hypothesis

2. Represent 2D or 3D representations of either very small or very large systems like microorganisms and solar system.

3. Used by the scientific communities to explain the complex scientific systems to people.

answer: the figure is attached herewith.

step-by-step explanation:   we are given to sketch a unit circle and label the terminal points corresponding to

in the attached figure, we have drawn a unit circle, with centre at o(0,0) and radius 1 unit. we have labelled the points a, b, c, d and e corresponding to the angles below

∠aox = 60°,

∠box = 120°,

∠cox = 180°,

∠dox = 240°,

∠eox = 300°.

and the coordinates are a(0.5,1), b(-0.5,1), c(-1,0), d(-0.5,-1) and e(0.5,-1).

thus, the answer is complete.

girl imma just put my comment here because i need a couple point okurrttt
