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.

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
If the terminal side of an angle beta is in quadrant III what is the sign of each of the trigonometric function value of beta?
Tangent and cotangent positive; other 4 negative.
Can reference angles be negative?
Certainly. A negative angle is simply clockwise instead of counterclockwise from the zero angle, but this is usually not indicated as such on a drawing.
What are the negative coterminal angles of 25 150 and 300?
To find negative coterminal angles, subtract 360 degrees from the given angles. For 25 degrees, the negative coterminal angle is (25 - 360 = -335) degrees. For 150 degrees, it is (150 - 360 = -210) degrees. For 300 degrees, the negative coterminal angle is (300 - 360 = -60) degrees.
What would be the angle between the ruler and its image if the angle between a horizontal ruler and a vertical plane mirror is 30?
30
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 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.
What is the difference between negative work and zero work and positive work done?
If the angle between the displacement and force applied is less than a right angle, then it is Positive Work done. If the angle between the displacement and the force applied is greater than a right angle then it is Negative Work done. If the displacement and force are at right angles, or either is zero, then it is Zero Work done.
How do you draw a negative 330 degree angle?
Since a circle is 360 degrees, negative 330 will look like positive 30, the difference between any two numbers on a clock face.
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.
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.
Is there a relationship between the sign positive or negative of the slope of a line and the angle the line makes with the x axis?
yes, the slope of the line is the tangent of the angle
Can dotproduct of two vectors be negative?
The dot-product of two vectors tells about the angle between them. If the dot-product is positive, then the angle between the two vectors is between 0 and 90 degrees. When the dot-product is negative, the angle is more than 90 degrees. Therefore, the dot-product can be any value (positive, negative, or zero). For example, the dot product of the vectors and is -1*1+1*0+1*0 = -1 which is negative.
Is there a relationship between the sign positive or negative of the slope of a line and the angle the line makes with the x-axis?
Yes.
How do you find the complement of a negative angle?
To find the complement of a negative angle, you first need to determine its positive equivalent by adding 360 degrees to the negative angle. Once you have the positive angle, you can then find its complement by subtracting the angle from 90 degrees. This will give you the complement of the negative angle in the range of 0 to 90 degrees.
Is a zero degree angle better than a positive or negative angle?
Better for what?
