## Is sin 1 the same as CSC?

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 ..

## What is the value for sin 45?

0.7071067812The value of Sin 45 degree in decimal form is 0.7071067812. Sine is considered as one of the most important functions in trigonometry as it is used to find out the unknown values of the angles and length of the sides of a right-angle triangle.

## What is sin 2x equal to?

By convention in Trigonometry, (sinx)2 is written as sin2 x, so # 3 is the correct answer.

## What does θ mean?

Theta (θ ) is a symbol used to denote the unknown measure of an angle. It is used mostly in displaying the trigonometric ratios of sine, cosine, and tangent. For example: sinθ=opphyp

## How do I calculate Theta?

The calculation of theta is expressed as a yearly value; however, the figure is often divided by the number of days in a year to arrive at a daily rate. The daily rate is the amount the value will drop by. A theta of -0.20 means that the price of an option would fall by $0.20 per day.

## What is cos 2x sin 2x?

Sin 2x cos 2x is one of the trigonometric identities which is essential for solving a variety of trigonometry related questions. Here, the simplified value of Sin2x cos2x is given along with the integral and derivative of sin2x and cos 2x.

## Why Sine is called sine?

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.

## What is value of theta?

Answered October 30, 2016 · Author has 177 answers and 461.4K answer views. Theta here is 90–22 = 68 degrees. In the right angled triangle, one vertex is 22 degree, second is 90 degree and the third is (90–22) degree. In short, the incident ray and the final reflected ray will be parallel to each other.

## What are the values of sin?

The function f(x) = sin x has all real numbers in its domain, but its range is −1 ≤ sin x ≤ 1. The values of the sine function are different, depending on whether the angle is in degrees or radians. The function is periodic with periodicity 360 degrees or 2π radians.

## Does theta have a value?

Theta is generally expressed as a negative number and can be thought of as the amount by which an option’s value will decline every day. Theta is drawn from the Greek alphabet and has numerous meanings across different fields.

## What is the value of sin 180 Theta?

θsin θcos θ90°10180°0−1270°−10360°011 more row

## What is sin of theta?

If θ is one of the acute angles in a triangle, then the sine of theta is the ratio of the opposite side to the hypotenuse, the cosine is the ratio of the adjacent side to the hypotenuse, and the tangent is the ratio of the opposite side to the adjacent side.

## Why is PH a sin?

Where x is the angle, o is the length of the triangle side opposite the angle and h is the length of the triangle’s hypotenuse. If the length of the triangle side opposite x is identified as p, then p/h is fine. I can see why using o as a variable name would be discouraged, since it is easily mistaken for a zero.

## What is sin 2 theta formula?

The first shows how we can express sin θ in terms of cos θ; the second shows how we can express cos θ in terms of sin θ. Note: sin2θ — “sine squared theta” — means (sin θ)2. Problem 3. A 3-4-5 triangle is right-angled.
