The domain of cosine is all real numbers, its range is [-1,1], and its period is 2π radians.
The Y-Intercept of the cosine function is X = 0, Y = cosine(0) = 1.
Yes. The cosine function is continuous. The sine function is also continuous. The tangent function, however, is not continuous.
The cosine function on a right triangle is Adjacent leg divided by the hypotenuse of the triangle.
The negative sine graph and the positive sine graph have opposite signs: when one is negative, the other is positive - by exactly the same amount. The sine function is said to be an odd function. The two graphs for cosine are the same. The cosine function is said to be even.
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.
The differential of the sine function is the cosine function while the differential of the cosine function is the negative of the sine function.
The domain of cosine is all real numbers, its range is [-1,1], and its period is 2π radians.
Cosine is a trigonometrical function.
The inverse of the cosine is the secant.
The Y-Intercept of the cosine function is X = 0, Y = cosine(0) = 1.
Yes. The cosine function is continuous. The sine function is also continuous. The tangent function, however, is not continuous.
The domain of a function is the set of values of the independent variable for which the function is valid. In practice, this is the allowable values of X or, in this case, theta. The sine and cosine functions have a domain of all numbers from negative infinity to positive infinity. The tangent function, however, is sine(theta) / cosine(theta). Cosine(theta) has value of zero at theta equal to pi / 2, 3pi/2, 5pi/2, ... in the positive direction, and -pi/2, -3pi/2, -5pi/2, ... As a result, tangent(theta) is undefined at these values, so the domain of tangent is all numbers from negative infinity to positive infinity except all numbers n pi/2 where n is odd.
False; the cosine function is an even function as cos(-x) = -cos(x).
I was not aware that the cosine function was in fashion!The range, on the other hand, is [-1, 1].
The argument of the cosine function must be (2pi/3)*x radians
The domains of polynomial, cosine, sine and exponential functions all contain the entire real number line. The domain of a rational function does not, since its denominator has zeros, and neither does the domain of a tangent function. (1/2)x = true (8/3)x = true
