240+360120 Since 120 is positive, you can stop here. To find this, add a positive rotation (360 degrees) until you get a positive angle.

It makes sense here to state the angle in terms of its positive coterminal angle.
#REFERENCE ANGLE HOW TO#
How to evaluate trig functions using reference angles Find the reference angle for the given angle. If you want a quick answer, have a look at the list below: Reference angle for 1: 1 Reference angle for 2: 2 Reference angle for 3: 3 Reference angle for 4: 4 Reference angle for 5: 5 Reference angle for 6: 6 Reference angle for 7: 7 Reference angle for 8: 8 Reference angle for 9. The reference angle is the angle from the sketch to the x-axis, in this case, 60 degrees. Depending on the quadrant in which t lies, the answer will be either be + or. Since is in Quadrant II, we subtract it from to get our reference angle: Report an Error. A: -120+360 240 degrees (coterminal) 240-180 60 degrees (reference) Example 3 Q: If the angle measure is 279 degrees, find the reference and two coterminal angles. An angle has the same properties as the reference angle.
#REFERENCE ANGLE PLUS#
is equal to two complete revolutions, plus a angle. A reference angle is an acute angle that has its initial side on the positive x-axis and terminal side in the first quadrant. Reference angle - angle formed by the coterminal ray and x-axis. To find the reference angle, we subtract for each complete revolution until we get a positive number less than.

I'm making worksheets to help students remember the unit circle and/or special triangles. What is The Reference Angle Theorem The Reference Angle Theorem states that To find the value of a trigonometric function of any angle t: Determine the function value for the associated reference angle t'. The reference angle is between and, starting on the positive -axis and rotating in a counter-clockwise manor.
