How do you find the six trig functions on the unit circle?

How do you find the 6 trigonometric functions?

Video quote: Okay ratios which the sine and the cosecant these are reciprocals of one another the cosine and the secant these are reciprocals of one another and the tangent the cotangent these are reciprocals.

How do you solve trig equations with a unit circle?

Video quote: So again our goal is to find angles on the interval from 0 to 2 pi that have a cosine function value of negative 1/2. Well in the unit circle the x coordinate is equal to cosine theta.

What are the 6 trigonometry ratios?

Review all six trigonometric ratios: sine, cosine, tangent, cotangent, secant, & cosecant.

What is the use of the six trig functions?

Lesson Summary. The six main trigonometric functions are sine, cosine, tangent, secant, cosecant, and cotangent. They are useful for finding heights and distances, and have practical applications in many fields including architecture, surveying, and engineering.

How do you graph 6 circular functions?

Video quote: Just so you understand what these tick marks are they're just halfway points. So for cosine we start at 1. We get to 0. At PI over 2 we go to negative 1. We go back to 0 and then back up.

How do you solve a circular function?

Video quote: But less than or equal to 360 degrees so we're solving this equation in degrees. So to start off with we want to really think about where does sine of x equal root 2 on 2 in the unit. Circle.

How do you find the cosecant?

The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x .

How do you find cosecant on the unit circle?

The cosecant function is the reciprocal of the sine function (cscx=1sinx) ⁡ x = 1 sin ⁡ . It can be found for an angle t by using the y -coordinate of the associated point on the unit circle: csct=1y ⁡ t = 1 y . The cotangent function is the reciprocal of the tangent function (cotx=1tanx=costsint) ⁡ x = 1 tan ⁡ ⁡ ⁡ .

What is the cosecant of?

In a right triangle, the cosecant of an angle is the length of the hypotenuse divided by the length of the opposite side. In a formula, it is abbreviated to just ‘csc’. Of the six possible trigonometric functions, cosecant, cotangent, and secant, are rarely used.

How do you do cosecant on a TI 84?

Video quote: So for example if we wanted to find the cosecant of 30 degrees. We have to use sine. So we start by entering the sine of 30 like we did before if we hit enter that gives us 0.5.

How do you solve trig functions on a TI 84?

Video quote: 1 alpha y equals it would get you to me my fraction. Button selecting one there now I can put in cosine of X on the bottom.

How do you do inverse trig functions on a TI 84?

Video quote: First we press the second key and then cosine for the inverse cosine. And negative 0.5 and enter the answer is 120 degrees or 2 PI over 3 radians. Again.

What is cosec in math?

Cosecant Formula. Cosecant is one of the six trigonometric ratios which is also denoted as cosec or csc. The cosecant formula is given by the length of the hypotenuse divided by the length of the opposite side in a right triangle.

What does csc mean in trig?

cosecant

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.

What is sec Trig?

The secant ( sec ⁡ ) (\sec) (sec)



The secant is the reciprocal of the cosine. It is the ratio of the hypotenuse to the side adjacent to a given angle in a right triangle.

What is the value of cosec 0?

undefined

The value of cosec 0° is given as undefined(∞).

What is the value sin0?

0

The value of sin 0° is 0.

What is the value of sin0 cosec0?

Answer. The value of cosec at 0° is the reciprocal of sin at 0°.

What is the value of cosec 1200?

Cosec 1200 degrees is the value of cosecant trigonometric function for an angle equal to 1200 degrees. The value of cosec 1200° is 2/√3 or 1.1547 (approx).

How do you find the value of cos120?

The value of cos 120 degrees can be calculated by constructing an angle of 120° with the x-axis, and then finding the coordinates of the corresponding point (-0.5, 0.866) on the unit circle. The value of cos 120° is equal to the x-coordinate (-0.5). ∴ cos 120° = -0.5.

What is the value of tan (- 585 )?

Tan 585 degrees is the value of tangent trigonometric function for an angle equal to 585 degrees. The value of tan 585° is 1.

How do you find the value of sin 4530?

Now, as we know the value of \[\sin \dfrac{\pi }{6}\] is given as \[\sin \dfrac{\pi }{6}=\dfrac{1}{2}\]. Hence, the value of M can be given as \[M=\dfrac{ -1}{2}\]. So, the value of \[\sin {{4530}^{o}}\text{ is }\dfrac{ -1}{2}\]. Hence, \[\dfrac{ -1}{2}\] is the answer.

What is the value of cot (- 15π 4?

So, the value of cot (-15π/4) is 1.
