What is cosec theta?

Cosec theta of a right-angled triangle

right-angled triangle

A right triangle, (also called a right-angled triangle), has one angle that is 90 degrees. The other two angles always add up to 90 degrees but can be different sizes. The side opposite to the right angle is the hypotenuse; it is the longest side in the right triangle.

is equal to the ratio of the length of the hypotenuse to the length of the opposite side.

What is cosec formula?

The cosecant formula is given as follows: cosec A = hypotenuse / opposite side = AB / BC = c / a. We know that, sin A = opposite side / hypotenuse. Cosecant is the reciprocal of sine.

What is cosec in math?

In a right angled triangle, the cosecant of an angle is: The length of the hypotenuse divided by the length of the side opposite the angle. The abbreviation is csc. csc θ = hypotenuse / opposite. It is not commonly used, and is equal to 1/sine.

What is the value of cosec?

The value of cosec 0 degrees is undefined(∞). Cosec 0 degrees in radians is written as cosec (0° × π/180°), i.e., cosec (0π) or cosec (0).

What is cosec theta minus cot theta?

Cosec theta minus cot theta whole square is equal to 1 minus cos theta by 1 + cos theta.

What is cosec 2x?

cosec^2x=cot^2x + 1, again...

How do you write Cot2x?

Cot2x is one of the important and commonly used trigonometric formulas. Mathematically, the formula for cot2x is written as cot2x = (cot^2x - 1)/(2cotx) = (cot²x - 1)/(2cotx). Cot2x can be expressed as combinations of different trigonometric functions and gives the value of cot function for double angle 2x.

What is the value of cosec 2?

Cosec 2 degrees is the value of cosecant trigonometric function for an angle equal to 2 degrees. The value of cosec 2° is 28.6537 (approx).

What is cosec 45?

Cosec 45 degrees is the value of cosecant trigonometric function for an angle equal to 45 degrees. The value of cosec 45° is √2 or 1.4142 (approx).

What is the value of cosec inverse?

Ex 2.1, 3 Find the principal value of cosec−1 (2) Let y = cosec−1 2 cosec y = 2 cosec y = cosec (?/?) ∴ y = ?/? Since Range of cosec-1 is [−π/2,π/2] – {0} Hence, Principal Value is ?/?.

What is the formula of sec2x?

Sec²x = 1 + tan²x.

What is cosec theta into cot theta?

cosec θ - cot θ = (1-cos θ )/sin θ

What is cos theta minus cot theta?

Cot theta-cos theta/ cot theta+cos theta=cosec theta-1/cosec theta+1.

What does cot theta equal?

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).

What is the value of theta?

In the system of Greek numerals, it has a value of 9.

What is the formula for cos θ?

It can be abbreviated as Cos(θ) and looks like this: Cos(θ) = adjacent/hypotenuse. In other words, it takes the length of the adjacent side (the side next to the angle) and divides it by the length of the hypotenuse (the longest side of a right triangle).
