cot(115º) = -tan(25)
or
cot(115º) = -0.466308
cot 81.1°
Cot(90) = 0 so 1/cot(90), if defined, would be 1/0. Such a fraction is not defined and that is what is wrong with the sentence.
For an angle, ?, the cotangent (or cot) of the angle is given bycot ? = 1/tan ?If ?=65
Cot(1.13 radians) = 0.4718
The Samsonite Travel Cot is used primarily for its portability and functionality. The Cot is used primarily for infants, and can be used on the go, and stored easily.
cot 115 deg = - tan25 deg
B: -tan(25)
There is no value cot 0, because cot 0 is equivalent to 1 / tan 0, which is equivalent to 1 / 0, which is undefined. That said, the limit of cot x as x approaches 0 is infinity.
cot 81.1°
Which expression is equivalent to cot t sec t
cot(360°) = cot(0°) = tan(90°) = ∞
cot(45 deg) = 1.
cot(-240) = -0.5774, approx.
First note that this not the graph of y = |cot(x)|.The equivalent equations for |y| = cot(x) or cot(x) = |y| arecot(x) = -y or cot(x) = +ySo plot y = cot x and then reflect all the points in the x-axis.
in second and fourth... for angles 135 and 315 degrees
All those can be calculated quickly with your calculator. Just be sure it is in "degrees" mode (not in radians). Also, use the following identities: csc(x) = 1 / sin(x) sec(x) = 1 / cos(x) cot(x) = 1 / tan(x) or the equivalent cos(x) / sin(x)
Cot(90) = 0 so 1/cot(90), if defined, would be 1/0. Such a fraction is not defined and that is what is wrong with the sentence.
