What is cosec function?

The cosecant function is the reciprocal of the trigonometric function sine. Cosecant is one of the main six trigonometric functions and is abbreviated as csc x or cosec x, where x is the angle. In 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.

Right triangle - Simple English Wikipedia, the free encyclopedia

, cosecant is equal to the ratio of the hypotenuse and perpendicular.

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?

Cosec theta of a right-angled triangle is equal to the ratio of the length of the hypotenuse to the length of the opposite side.

What is cosec 2x?

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

What is the integration of Cosecx?

The integral of cosec x is denoted by ∫ cosec x dx (or) ∫ csc x dx and its value is ln |cosec x - cot x| + C. This is also known as the antiderivative of cosec x. We have multiple formulas for this. But the more popular formula is, ∫ cosec x dx = ln |cosec x - cot x| + C.

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 the formula for tan2x?

The formula for tan2x identity is given as: tan2x = 2tan x / (1−tan²x) tan2x = sin 2x/cos 2x.

What is the relation between cot and cosec?

Hence, proved that (cosec θ – cot θ)² = (1 – cos θ)/(1 + cos θ).

What is cot theta formula?

The cotangent formula for an angle θ is: cot θ = (Adjacent side) / (Opposite side). Let us take a look at the right-angled triangle ABC that is right-angled at B. Then AB is the side that is adjacent to A and BC is the side that is opposite to A.

What is the value of cosec (- 1410 degree?

The value of cosec 1410° is given as -2.

What is cosec 180?

csc(180°)=1sin(180°)=10 . Because we're dividing by 0, it is undefined.
