the answer is 180 degrees; since cos 180⁰ = -1, then cos-1 -1 = 180⁰
mathematically
cos-1-1
here calculator is required
and you'll get answer 180 degrees.....

Which angle has a negative sine and a positive cosine?
All the angles in 4th quadrant have positive cosine and negative sine e.g. 280,290,300,310...etc.
What is cosine to the negative first power?
[ cos(Θ) ]-1 = 1/cosine(Θ) = secant(Θ)
Is the inverse function of secant is the cosecant function?
No. The inverse of the secant is called the arc-secant. The relation between the secant and the cosecant is similar to the relation between the sine and the cosine - they are somehow related, but they are not inverse functions. The secant is the reciprocal of the cosine (sec x = 1 / cos x). The cosecant is the reciprocal of the sine (cos x = 1 / sin x).
What is the multiplicative inverse of negative 9?
-9; the multiplicative inverse: -1/9
What does mean additive inverses?
The additive inverse of a number is the negative of that number. Given one number, its additive inverse is the number that needs to be added to it so that the sum is zero. Thus: The additive inverse of 2.5 is -2.5 The additive inverse of -7.998 is 7.998
What is an inverse cosine?
The inverse of the cosine is the secant.
The inverse of the cosine function?
The inverse of the cosine is the secant.
Is the inverse cosine of 0.55?
The inverse if cosine 0.55 is 0.55
Why do cosine to the negative 1th power and cosine cancel out each other?
Cosine to the negative first power and cosine cancel each other out because cosine to the negative first power is one over cosine, and one over anything times anything is just one.
What is cosine inverse of pi?
udefined
What is the inverse of the cosine function?
The inverse of the cosine function is arcosine. The domain is −1 ≤ x ≤ 1 since the range of the cosine function is from -1 to 1. The range is from 0 to pi radians or 0 to 180 degrees.
What does csc stand for on a calulator?
Cosecant, or the inverse of the cosine.
What is an arccosh?
An arccosh is the inverse hyperbolic cosine function.
What is the derivative of negative cosine?
The derivative of negative cosine is positive sine.
What is the multiplicative inverse of negative one ninths?
negative 9.
What is the multiplication inverse of negative 3?
negative one third.
How a negative affects a multiplicative inverse?
A number and its multiplicative inverse have the same sign. So if one is negative, so is the other.
