Показать описание
👉 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. The 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.

Whoever invented this math should be put in prison

Can it terminate on the y axis? If so, if i have 5pi/3 I wouldnt use the same equation to find the reference angle, right? So would i just use a different denominator. Or would i terminate on 4pi/3. Im confused

why did you subtract 6pi/3 when you said to subtract 2pi
just confused

When you know it's time for you to consider a different major:
