The exact value of sec(30°) sec ( 30 ° ) is 2√3 . Multiply 2√3 by √3√3 . Combine and simplify the denominator. Multiply 2√3 2 3 and √3√3 3 3 .
What is the exact value SEC?
The exact value of sec(0) is 1 .
What is the exact value csc 30?
The exact value of csc(30) is 2 .
What fraction is cos 30?
Cos 30 degrees is written as cos 30° and has a value in fraction form as √3/2. Cos 30° = √3/2. Cos 30° = √3/2 is an irrational number and equals to 0.8660254037 (decimal form). Therefore, the exact value of cos 30 degrees is written as 0.8660 approx.
How do you find a cot?
The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x .
How do you find the value of sec 0?
The value of sec 0 degrees can be calculated by constructing an angle of 0° with the x-axis, and then finding the coordinates of the corresponding point (1, 0) on the unit circle. The value of sec 0° is equal to the reciprocal of the x-coordinate(1). ∴ sec 0° = 1.
How do you evaluate SEC 3pi 2?
Angle 3π2 corresponds to a point with coordinates (0,−1) on a unit circle. Therefore, cos(3π2)=0 . Since sec(3π2)=1cos(3π2) and cos(3π2)=0 , the value of sec(3π2) is undefined.
What is secant squared of pi over 3?
The exact value of sec(π3) sec ( π 3 ) is 2 .
What is sin 30 degrees?
The exact value of sin 30 degrees is ½.
What fraction is sin 30?
Sin 30 degrees is the value of sine trigonometric function for an angle equal to 30 degrees. The value of sin 30° is 1/2 or 0.5.
How do you write Cosecant?
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, cosecant is equal to the ratio of the hypotenuse and perpendicular. Since it is the reciprocal of sine, we write it as csc x = 1 / sin x.
