What is the cosine of -90?
Cosine of -90 is 0.
What is the ratio that is the reciprocal of the cosine?
it would be secant, 1/cosine
What is cosine to the negative first power?
[ cos(Θ) ]-1 = 1/cosine(Θ) = secant(Θ)
What is the cosine of 45?

How do you use cosine?
cosine = adjacent/hypotenuse. It can be used as other trig functions can.
Why are sine and cosine functions used to describe periodic?
because sine & cosine functions are periodic.
What is cosine cubed?
It is cosine*cosine*cosine.
Which angle length does cosine give you?
Sides have lenght, angles do not. Cosine is the ratio of the adjacent side to the hypotenuse. Cosine can be used to find either of these sides if the other is known.
Where to use sine and cosine in physics?
The sine, cosine and tangent are used to find the degrees of a right angle triangle.
The laws of sine cosine and tangent are used where?
in trigonometry
What types of math is used in pool?
sine and cosine
What is cosine 0?

What is the cosine of 3.14?
what is the cosine of 3.14 ?
What is cosine of 1?
Cosine of 1 degree is about 0.999848. Cosine of 1 radian is about 0.540302.
How does the tangent function relate to sine and cosine?
Tangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.
What is the cosine of 6 degrees?
Cosine is 0.995
