What is the cot of 30 degrees?
The exact value of cot(30°) cot ( 30 ° ) is √3 .
What is the value of cot 45 degree?
Trigonometry Examples The exact value of cot(45°) cot ( 45 ° ) is 1 .
Why is cot 180 undefined?
…and note that the sine of a 180 degree angle is zero, and the cosine of that angle is -1. So, this evaluates to a division by zero. Therefore, cot180 is undefined.
What is Cosec 180?
Nikun answered this. Take cosec 180 as zero . It is due to a rule in which after pie or 180 degree same value follow. It is infinity but you take it zero. Also for sine For cos and sec take -1.

What is the exact value of sin 240?
240 degrees is in the third quadrant, where the sin of the angle is negative. Subtracting 180 degrees from 240 degrees, you can see that the reference angle is 240-180 = 60 degrees.
What is tan (- theta?
The law of Tangent which is also called as tangent formula or tangent rule is the ratio of the sine of the angle to the cos of the angle. Tan Θ = Opposite / Adjacent.
What is sin minus theta?
trigonometric ratios of minus theta|sin(−Θ)=−sinΘ ,cos(−Θ)=cosΘ
What is the formula for 1 sin theta?
(Math | Trig | Identities)
| sin(theta) = a / c | csc(theta) = 1 / sin(theta) = c / a |
|---|---|
| cos(theta) = b / c | sec(theta) = 1 / cos(theta) = c / b |
| tan(theta) = sin(theta) / cos(theta) = a / b | cot(theta) = 1/ tan(theta) = b / a |
What is cot theta equal to?
The reciprocal cosine function is secant: sec(theta)=1/cos(theta). The reciprocal sine function is cosecant, csc(theta)=1/sin(theta). The reciprocal tangent function is cotangent, expressed two ways: cot(theta)=1/tan(theta) or cot(theta)=cos(theta)/sin(theta).
