The argument of the cosine function must be (2pi/3)*x radians
It doesn't exist. The maximum value of the cosine is 1.00, so no angle can have a cosine of (pi), because (pi) is more than 3.
Cosine(30) = sqrt(3)/2
-sqrt(3) / 2
what is the cosine of 3.14 ?
The argument of the cosine function must be (2pi/3)*x radians
cos(30) = sqrt(3)/2 so cosine squared is 3/4.
It doesn't exist. The maximum value of the cosine is 1.00, so no angle can have a cosine of (pi), because (pi) is more than 3.
Cosine(30) = sqrt(3)/2
-sqrt(3) / 2
It is cosine*cosine*cosine.
The integral of cosine cubed is sinx- 1/3 sin cubed x + c
0.866 ( or (sqrt 3)/2 )
what is the cosine of 3.14 ?
Cosine of 1 degree is about 0.999848. Cosine of 1 radian is about 0.540302.
Tangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.
