Unit circle:
As we had studied enough on circle and its types. Today let me help you on unit circle chat. A unit circle is a circle whose radius = 1 unit and center is ( 0,0). Angles are measured using this chart, angles measure clockwise would have positive values and angles measured in anticlockwise have negative values.
Following are the sample graph of unit circle chat.
On unit circle line inverse trigonometric functions are given as X = Cos and Y = sin
The value of sine is on the y coordinate of unit circle and value of cosine is on the x coordinate of unit circle. Using the unit circle any trigonometric function value can be calculated by using certain formulas. We divide the unit circle into 4 quadrants.
Did i really help you on this? I understand you still need more help on more topics like this. Keep reading and leave your comments so that i can help you particularly on your problems. May be in the next session let me help you on Adjacent Angles
