What is the reference angle of data 540 degrees and evaluate the six trigonometric functions of data.
..
540º angle means the terminal side went 360º counter-clockwise then another 180º ending on the x-axis. The reference angle is actually zero but we think of it as 180º. Six trigonometric functions at 180º follows:
sin 180º=0
cos 180º=-1
tan 180º=0
csc 180º=undefined
sec 180º=-1
cot 180º=undefined
