Is negative value possible inside an anti-log?
No. The range of the exponential (antilog) function is the positive reals (unless you are dealing with the complex field).
What does it mean when an angle is negative?
An angle is a measure of turn. the amount of turn is the magnitude, measured in degrees, and direction of turn can be clockwise or anti-clockwise. A positive angle turns in an anti-clockwise direction while a negative angle turns in a clockwise direction.
Why do counterclockwise angles has positive signs?
Conventionally, angles in the coordinate plane are measured, starting from 0 along the x-axis and increasing in the anti-clockwise direction.
Why is the first quadrant the first quadrant?
It 2-dimensional coordinate geometry, angles are measured from the origin, relative to the positive direction of the x-axis and they increase in the anti-clockwise direction. As a result, small positive angles are in the first quadrant, and as the angle size increases it moves into the second, third and fourth quadrants.
Is a paper clip paramagnetic?
No, just very weakly ferromagnetic. Unless your paperclip is made out of NH4[Fe(SO4)2]·12H2O.
