    Sketch Radians in Standard Position

    Working through a trig book and I was asked to sketch a number in radians in standard position. Just wanted to verify I did this correctly beaus the book does not work through the problem. EDIT: Just noticed in the diagram I forgot to invert pi/2 and 3pi/2, but other than that this was the answer I came up with.

    If you want to draw angles in standard position, you have to start from the positive x-axis (0 radian or 0 degree) going around till the required angle.

    Here is a video that can help you!

    The "circular arrow" you have drawn, from the base angle to the negative x-axis, which if I were your teacher I would interpret as representing the given angle, is NOT "-2.6 radians". The correct angle is from the positive x-axis to that position.

    Did I implement your feedback correctly here? Starting at the x-axis and moving to the required angle.Sketch Radians in Standard Position-asd.png

    Yes, that is the correct angle.
