Yes. Angles may be measured from the direction of the positive horizontal axis and, clockwise is negative, anticlockwise is positive.

When is an angle positive?
An angle is positive when it is measured in a counter-clockwise direction. It is negative when it is measured in a clock-wise direction.
Positive and negative angles?
In the Cartesian plane, an angle is measured in the anti-clockwise direction from the x-axis. A negative angle is measured in the clockwise direction from the x-axis. However, an angle is effectively the same if you add or subtract 360 degrees. So, if you are faced with a negative angle just keep adding 360 degrees until you have a positive value.
What is a negative - positive?
Negative * positive = negative Positive * positive = positive Negative * negative = positive
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.
When multiplying numbers what do you do with the positive and negative signs?
Negative * positive = negative Positive * positive = positive Negative * negative = positive
What are positive and negative angle?
positive and negative angles of 87 degrees
What is cos of a negative angle?
The cosine function is an even function which means that cos(-x) = cos(x). So, if cos of an angle is positive, then the cos of the negative of that angle is positive and if cos of an angle is negative, then the cos of the negative of that angle is negaitive.
Is a zero degree angle better than a positive or negative angle?
Better for what?
When is an angle positive?
An angle is positive when it is measured in a counter-clockwise direction. It is negative when it is measured in a clock-wise direction.
What is difference between positive and negative rake angle?
The clear difference between positive and negative rake angles is that for the positive rake angle,the leading edge of the cutting tool is behind the perpendicular of the material to be cut.While the tool leading edge is ahead or beyond the perpendicular for the negative rake angle.
Which angle has a negative sine and a positive cosine?
All the angles in 4th quadrant have positive cosine and negative sine e.g. 280,290,300,310...etc.
What is a line wxtending from the upper lift to the lower right has this type of slope?
The line has a negative slope (or negative gradient).When the angle between the line and the positive direction of Ox is obtuse then the slope is negative. Conversely, when the angle is acute, the slope is positive.
Positive and negative angles?
In the Cartesian plane, an angle is measured in the anti-clockwise direction from the x-axis. A negative angle is measured in the clockwise direction from the x-axis. However, an angle is effectively the same if you add or subtract 360 degrees. So, if you are faced with a negative angle just keep adding 360 degrees until you have a positive value.
What is the difference between angle of attack and positive angle of attack?
Angle of attack may be negative or positive - it's simply the angle between the wing chord line and the oncoming airflow. If it's positive then the aircraft will benefit from the lift that is provided, if it's negative then there is no lift (but there's still drag). This is a potentially dangerous situation, unless you wish your aircraft to descend.
Why the value of cos positive for negative value of angle?
The cosine of an angle is the adjacent side of the angle of a triangle divided the hypotenuse. If you plot the adjacent side as x on an x -y graph, for negative angles less than 90 degrees the adjacent side is positive and the hypotenuse is always positive, so you get a positive. The cosine is positive int e upper right and lower right quadrants
What is the difference between positive and negative angles?
Essentially, none. Every negative angle can be made positive by adding 2*pi radians (or 360 degrees, or a multiple).
What is azimouth algorithm?
The solar Azimuth angle shows the angle of the sun. This algorithm states the angle is positive if the line is east of south and negative if it is west of south.Ê
