What is Cot theta: The inverse tangent function is the cotangent, expressed in two ways: cot( **theta)=1/tan(theta** ) or cot(theta)=cos(theta)/sin(theta).

Also, what does it mean when sin is less than 0?

Quadrant II – sine is positive, cosine and tangent are negative. Quadrant IV – sine and tangent are negative, cosine is positive. The most appropriate quadrant for your description is the quadrant IV because sin theta must be less than 0 and cos theta must be greater than 0.

Here, what is 30 degree cot?

cot(30°) The correct value of cot ( 30° ) is **3** .

Also to know what is the antonym of cos? NS is the reciprocal of the **biting cosine. **It is the ratio of the hypotenuse of a right angled triangle to the adjacent angle of the given angle.

Which quadrant is sin negative?

So sine will be negative if y is negative, which is in the **third and fourth quadrants** . So the tangent is negative in QII and QIV, and the sine is negative in QIII and QIV.

**Which quadrant sin is less than 0?**

The only quadrant where x is positive, so cos(x)>0 , and y is negative, so sin(x)<0 , is the **fourth quadrant** .

**What is ASTC rule?**

ASTC is the abbreviation for the ‘All Sin Cos Tan’ rule in trigonometry. The first letter of the third word T indicates that the tangent in the third quadrant and its inverse is positive. … the first letter of the last word C indicates that the cosine and its inverse are positive in the fourth quadrant.

**How do you find the cot 45 degrees?**

cot(45°) The correct value of cot ( 45° ) is **1** .

**What is the Cradle of 60?**

The correct value of cot(60) is **1** .

**What is CSC and COT?**

The cotangent of x is defined as the cosine of x divided by the sine of x: cot x = cos x sin x. The secant of x 1 is divided by the cosine of x: sec x = 1 cos x, and the cosecant of x divided by the sine of x 1 is defined as: **csc x = 1 sin x** .

**Is cot tan 1?**

**Where is point XY located?**

The horizontal axis in the coordinate plane is called the x-axis. The vertical axis is called the y-axis. The point at which two axes intersect is called **origin** . The origin is at 0 on the x-axis and 0 on the y-axis.

**Where is CSC negative?**

Therefore, the covariance of angles:

The one that ends in quadrants I and II is positive; that finally **quadrants III and IV** are negative.

**Can the hypotenuse be negative?**

So by this logic, the hypotenuse (and any length, for that matter) of a triangle can **not be negative** and therefore must be positive.

**The value of sin is 0?**

Answer) In mathematics the value of sin 0 degree is **always 0 . equal to** .

**Why is tan positive quadrant 3?**

The tangent is positive for angles in quadrant III on their last side, since **sine is negative and cosine is negative .**

**Quadrant 4 is positive or negative?**

In quadrant I, both the x- and y-coordinates are positive; In Quadrant II, the x-coordinate is negative, but the y-coordinate is positive; Both are negative in quadrant III; And in quadrant IV, **x is positive but y is negative** .

**How do I remember ASTC?**

**All students take calculus** . Each quadrant of the plane has a mnemonic for the sign of each of the trigonometric functions. The letters ASTC indicate which trigonometric functions are positive, starting in the top right quadrant 1 and running counterclockwise through quadrants 2 through 4.

**Is cos 93 positive or negative?**

What is cos 93°? In a circle with radius r, horizontal axis x and vertical axis y, 93° is the angle formed by two sides x and r; r is moving counterclockwise **positive** angle.

**How do you find cot 45 without a calculator?**

Using a reference triangle and the ratio of A/O, we can find the cotangent of 45. Answer: (((sqrt(2))/2)/((sqrt(2))/2)), then can be simplified to **cot(45) = 1** . Hope this will help!

**What is the value of cot 30 and cot 45?**

Cosec **30** + **Cot45** =2+1=3. As in 3. Option C is the correct answer.

**Why is 45 degrees a special angle?**

So the sides of every 30,60,90 right triangle are approximately 0.5/0.866/1.0 in a particular ratio. – Basic trigonometry uses the ratio of ‘angle size’ to ‘side length’ of respective triangles. The angle of 45 degrees is also **special because it is found twice in every isosceles triangle** .
