FAQ: What Is Cotangent In Math?

What is Cotangent equal to?

The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x. 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. = tan 5π 4. tan x = −∞.

How do you find Cotangent?

The cotangent of an angle in a right triangle is a relationship found by dividing the length of the side adjacent to the given angle by the length of the side opposite to the given angle. This is the reciprocal of the tangent function.

What is a Cosecant 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.

Is COT the same as tan 1?

Using the tan 1 x convention may lead to confusion about the difference between arctangent and cotangent. It turns out that arctan and cot are really separate things: cot (x) = 1 / tan (x), so cotangent is basically the reciprocal of a tangent, or, in other words, the multiplicative inverse.

What is the reciprocal of cot?

The reciprocal cosine function is secant: sec(theta)=1/cos(theta). 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).

Is sin 1 the same as CSC?

cosecant is the reciprical of the sin function or 1 / sin (x) so that csc (x)* sin (x) = 1 when it is defined. The two can be confused since arcsin(x) is often denoted as sin ^- 1 (x) and x^- 1 is 1 /x.

What quadrant is sin positive?

All the trig functions are positive in Quadrant 1. Sine and cosecant are positive in Quadrant 2, tangent and cotangent are positive in Quadrant 3, and cosine and secant are positive in Quadrant 4.

What is tan on the unit circle?

Instead, think that the tangent of an angle in the unit circle is the slope. If you pick a point on the circle then the slope will be its y coordinate over its x coordinate, i.e. y/x. So at point (1, 0) at 0° then the tan = y/x = 0/1 = 0.

What is Secand?

In geometry, a secant of a curve is a line that intersects the curve at a minimum of two distinct points. In the case of a circle, a secant will intersect the circle at exactly two points.

What is CSC in terms of sin?

The cosecant ( csc ⁡ ) ( csc ) ( csc ) The cosecant is the reciprocal of the sine. It is the ratio of the hypotenuse to the side opposite a given angle in a right triangle.

What is sin equal to?

Always, always, the sine of an angle is equal to the opposite side divided by the hypotenuse (opp/hyp in the diagram). The cosine is equal to the adjacent side divided by the hypotenuse (adj/hyp). (1) Memorize: sine = (opposite side) / hypotenuse. cosine = (adjacent side) / hypotenuse.

What sine means?

In mathematics, the sine is a trigonometric function of an angle. The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle, to the length of the longest side of the triangle (the hypotenuse).
