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.
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 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.
What is the coplement of a 55 degree angle?
The complement of a 55 degree angle is a 35 degree angle
What type of angle is a 12 degree angle?
A 12 degree angle is an acute angle.
What are positive and negative angle?
positive and negative angles of 87 degrees
What is angle of reference in trigonometry?
This is a VERY important question and I am glad you asked it. First you have to remember that in drawing angles we think of 4 quadrants. Think of the XY plane - the first quadrant is where BOTH X and Y are positive. In the 2nd quadrant the X is negative and the Y is positive. In the 3rd quadrant the X and the Y are negative. In the 4th quadrant the X is positive and the Y is negative. Normally when we draw an angle we draw an angle less than 90 degrees. However, we can draw any angle we want from 0 to 360. However that angle can be represented by an angle less than 90 degrees in a certain quadrant. Take an angle like 120 degrees. That angle is the same as a 60 degree angle in the 2nd quadrant. A 210 degree angle is the same as a 30 degree angle in the 3rd quadrant. A 359 degree angle is the same as a 1 degree angle in the 4th quadrant. Those smaller angles are reference angles. This explanation would be better if I could insert graphs. I have attached a link to a picture. Alpha is the angle and Beta is the reference angle.
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.
Definition a 135 degree angle?
It is a 90 degree angle, or a right anlge, plus another 45 degrees. So you can visualize it as a 45 degree angle measured from the negative side of the x axis going toward the positive y axis on the x-y plane.
What is 10 a degree angle?
A line which rotates through an angle of 10 degree with the positive side of the x-axis of the Cartesian plane is called a 10 degree angle.
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.
Is there a positive or a negative angle?
Yes. Angles may be measured from the direction of the positive horizontal axis and, clockwise is negative, anticlockwise is positive.
Is zero degree an acute angle?
A non negative angle which is less than 90 degrees is an acute angle. So, Zero degree is an acute angle.
What is the reference angle of -370 degree?
A reference angle is the positive angle less than 360 which is coterminal with the given angle. For a negative angle add 360 repeatedly until you gat an answer less than 360. =370 + 360 = -10 -10 +360 = 350
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 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.
