Determine the Quadrant in which the Angle Lies
 
03:11
Learn how to sketch angles in terms of pi. An angle is the figure formed by two rays sharing the same endpoint. Angle is measured in radians or in degrees. One complete revolution about a point is equivalent to 2pi radians and 360 degrees. Angle measured in the anti-clockwise direction is called a positive angle while a negative angle is measured in the clockwise direction. We measure angles starting from the positive x-axis. To sketch an angle in terms of pi, we make use of the knowledge that the angle made by a circle is 2pi and that made by a straight line is pi. So, we first sketch a circle which we will divide into two. Next we divide each half of the circle into the number of parts corresponding to the denominator of the angle we want to sketch. The number of parts corresponding to the numerator of the angle we are sketching from the 0 radians point is the angle we are looking for. #trigonometry #sketchangles #trigonometry #anglesintrigonometry

How to find the estimate of an angle in radians - Help me on math

Learn about angles in trigonometry. An angle is the figure formed by two rays sharing the same endpoint. The two rays are called the sides of the angle while the common endpoint of the two rays is called the vertex of the angle. Angle is measured in radians or in degrees. The radian is the measure of the length of an arc of a unit circle or the measure of the radius of the circle on the circumference of the circle. pi radians is equivalent to 180 degrees. One complete revolution about a point is equivalent to 2pi radians and 360 degrees. A plane is usually divided into 4 equal parts called the quadrants. Angle measured in the anti-clockwise direction is called a positive angle while a negative angle is measured in the clockwise direction. We measure angles starting from the positive x-axis. #trigonometry #sketchangles #trigonometry #anglesintrigonometry

A negative angle larger than one revolution to find the quadrant of the terminal side
 
02:43
Learn how to determine the quadrant of an angle given in degrees. Recall that the circumference of a circle is equivalent to 360 degrees. Also recall that each quadrant is equivalent to 90 degrees. To determine the quadrant of the angle given in degrees, we determine the number of 90 degrees in the given angle. The quadrant where the remainder of the given angle that is not up to the next multiple of 90 lies corresponds to the quadrant of the given angle. For angles greater than 360 degrees, we first make the number of 360 degree turns in the given triangle before determining the number of 90 degrees in the remainder that is not up to the next multiple of 360 degrees. Note that the direction is in an anti-clockwise direction for positive angles and in the clockwise direction for negative angles from the positive x-axis.

Find the Values of Theta in Degrees and Radians in First Quadrant

Learn how to evaluate inverse tangent function using the unit circle. When an angle is unknown but the value of the tangent function of the angle is known, we can evaluate the value of the angle using the inverse tangent function of the known tangent function. For instance, if we know that tan x = a/b where x is unknown and a, b are known, then we an evaluate x by x = arctan (a/b). The inverse tangent function is denoted by 'arctan' or tan^(-1). With the unit circle, we can determine the angle corresponding to the terminal point for which the value of its tangent is given. We then apply the necessary restrictions to obtain the required angle. #trigonometry #inversefunctions

To determine the quadrant of the angle given in degrees, we determine the number of 90 degrees in the given angle.

Sketch the Graph in Standard Position when Over 2PI

Learn how to sketch angles in terms of pi. An angle is the figure formed by two rays sharing the same endpoint. Angle is measured in radians or in degrees. One complete revolution about a point is equivalent to 2pi radians and 360 degrees. Angle measured in the anti-clockwise direction is called a positive angle while a negative angle is measured in the clockwise direction. We measure angles starting from the positive x-axis. To sketch an angle in terms of pi, we make use of the knowledge that the angle made by a circle is 2pi and that made by a straight line is pi. So, we first sketch a circle which we will divide into two. Next we divide each half of the circle into the number of parts corresponding to the denominator of the angle we want to sketch. The number of parts corresponding to the numerator of the angle we are sketching from the 0 radians point is the angle we are looking for. #trigonometry #sketchangles #trigonometry #anglesintrigonometry

Sketch the Angle in Standard Position

Learn how to sketch an angle in degrees in standard form. An angle is the figure formed by two rays sharing the same endpoint. Angle is measured in radians or in degrees. One complete revolution about a point is equivalent to 2pi radians and 360 degrees. Angle measured in the anti-clockwise direction is called a positive angle while a negative angle is measured in the clockwise direction. We measure angles starting from the positive x-axis. To sketch an angle in degrees, we first sketch a circle which we will divide into 4 equal parts. We note that each of the four equal parts measures 90 degrees. We also note that one complete revolution round the circle is 360 degrees. Next we can use divisions into factors of 90 degrees to estimate the position of the angle we are sketching. #trigonometry #sketchangles #trigonometry #anglesintrigonometry

Learn how to sketch angles in radians. An angle is the figure formed by two rays sharing the same endpoint. Angle is measured in radians or in degrees. One complete revolution about a point is equivalent to 2pi radians and 360 degrees. Angle measured in the anti-clockwise direction is called a positive angle while a negative angle is measured in the clockwise direction. We measure angles starting from the positive x-axis. To sketch an angle in radians, we make use of the knowledge that the angle made by a circle is 2pi and that made by a straight line is pi. We also make use of the knowledge that pi is approximately 3.142. So, we first sketch a circle which we will divide into two. Next we divide the circle in such a way that the third division is just abov the halfway point of the circle. and the 6th division is just before one revolution about the center of the circle. The number of parts corresponding to the angle we are sketching from the 0 radians point is the angle we are looking for. #trigonometry #sketchangles #trigonometry #anglesintrigonometry

College Algebra and Trig II: Angles and Their Measures
 
14:04
In this lecture, we discuss the components of an angle, the relationship between degrees, radians, and revolutions, converting between radians and degrees; converting from decimal degrees to degree/minute/second notation; arc length; and area of a sector.
