Are you supposed to memorize the unit circle?

Memorizing the unit circle is actually much easier than you’d think, thanks to a couple little tricks: Trick 1: Because of the following 4 equations, we only need to memorize the unit circle values for sine and cosine.

Is there an easy way to memorize the unit circle?

Recognize each quadrant shares the denominators 6, 4, and 3. This makes it easier to memorize the radians. The number 3 is always close to the y-axis, while the number 6 is always close to the x-axis.

Is tan sin over COS?

The tangent of x is defined to be its sine divided by its cosine: tan x = sin x cos x . The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x .

Is tan y x on the unit circle?

The unit circle definition is tan(theta)=y/x or tan(theta)=sin(theta)/cos(theta). The tangent function is negative whenever sine or cosine, but not both, are negative: the second and fourth quadrants. Tangent is also equal to the slope of the terminal side.
