What is the value of Cos n 2π=???

1 answer:

5 0

If n is an integer, then cos(n(2<span>π))=1.

Take n=0, cos(2</span>π)=cos(0)=1, n=1, cos(2π)=1, n=2, cos(2(2π))=cos(4<span>π)=cos(0)=1...

If n is not an integer, well, ..... we don't know the value, which depends on the value of n.</span>

The scale of a drawing is 2 cm : 1 mm. Is the scale drawing larger or smaller than the actual object? Explain.

The scale drawing is smaller than the actual object because a scale is an estimation on where an object is. We can't draw 1 mile that would be impossible to draw a whole drawing based on one location.
