# Does Sin Start At 1?

## Can a sine be greater than 1?

In a right triangle, the sine of an angle is the ratio of the length of the opposite side divided by the length of the hypotenuse.

Because a ≤ c, sin ∠A ≤ 1 (the only way sin∠A = 1 is if a = c, but that would make for a strange triangle!), the sine ratio cannot be greater than 1..

## Why is tan greater than 1?

Because in a triangle with one right angle, the diagonal c is always longer than the two others a and b, making the ratios a/c and b/c (which we call sine and cosine) both smaller than 1. There is no such restriction on the length of a and b, so their ratio (which we call the tangent) can get any value.

## Can Cos be more than 1?

Since adjacent side can never be greater than hypotenuse, cosine of an angle cannot be greater than 1.

## Where is angle of depression?

The angle of depression is the angle between the horizontal and your line of sight (when looking down). Now, pretend that the spot on your kitchen floor could look back up at you.

## Is sin 1 the same as 1 sin?

The notation sin-1(x) has been misunderstood to mean 1/sin(x). … So sin-1(x) means the inverse sine of x, that is, the function that undoes the sine function. It is not equal to 1/sin(x).

## Does Arcsin sin 1?

An arc function undoes a trig or hyperbolic trig function. Strictly speaking, the symbol sin-1( ) or Arcsin( ) is used for the Arcsine function, the function that undoes the sine. This function returns only one answer for each input and it corresponds to the blue arcsine graph at the left.

## How do you find sin 45?

Sine function defines a relation between the acute angle of a right-angled triangle and the opposite side to the angle and hypotenuse….Sin 45° = \sqrt{2/4} = 1/\sqrt{2}Sine 0°0Sine 30° or Sine π/61/2Sine 45° or Sine π/41/\sqrt{2}Sine 60°or Sine π/3\sqrt{3}/2Sine 90° or Sine π/215 more rows

## How do you find the sin of 1?

Inverse Sine FunctionStart with:sin a° = opposite/hypotenuse.sin a° = 18.88/30.Calculate 18.88/30:sin a° = 0.6293…Inverse Sine:a° = sin−1(0.6293…)Use a calculator to find sin−1(0.6293… ):a° = 39.0° (to 1 decimal place)

## Can the sine of an angle be 2?

23) Can the sine of an angle ever equal 2? Why or why not? No, the hypotenuse > opposite side.

## Why Sine is called sine?

In mathematics, the sine is a trigonometric function of an angle. … The word “sine” (Latin “sinus”) comes from a Latin mistranslation by Robert of Chester of the Arabic jiba, which is a transliteration of the Sanskrit word for half the chord, jya-ardha.

## Where is tan equal to 1?

The exact value of arctan(1) is π4 . The tangent function is positive in the first and third quadrants. To find the second solution, add the reference angle from π to find the solution in the fourth quadrant.

## Can the hypotenuse be negative?

Because it is the length of the side of a triangle and lengths cannot be negative.

## What is the sin of 1 in radians?

0.8414709848The value of sin 1 is 0.8414709848, in radian. In trigonometry, the complete trigonometric functions and formulas are based on three primary ratios, i.e., sine, cosine, and tangent in trigonometry.

## 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 is the value of sin 1 0?

The answer isn’t limited to a range of values, so the exact value is: sin−1(0)=nπ where n is an integer – this allows us to express not just 0 degrees but also π,2π,3π,−π,−2π and so on.

## What is the exact value of sin 1 (- 1?

The Value of the Inverse Sin of 1 As you can see below, the inverse sin-1 (1) is 90° or, in radian measure, Π/2 . ‘1’ represents the maximum value of the sine function . It happens at Π/2 and then again at 3Π/2 etc..

## Why is sin less than 1?

The value of sin and Cos is always less than 1 because sin is equals two perpendicular ÷ hypotenuse and perpendicular is always smaller than hypotenuse so it is not possible that sin is greater than 1 same case in cos also cos is equals to base divided by hypotenuse and base is always smaller than hypotenuse so it is …
