## What is the formula of 1-cos theta upon sin theta?

1-cos theta /sin theta =sin theta / 1+cos theta.

## What is formula of cos theta?

Cos θ = Adjacent/Hypotenuse. Here θ represents the angle of a triangle. The angles by which trigonometric functions can be represented are called trigonometry angles. The important angles of trigonometry are 0°, 30°, 45°, 60°, 90°.

## What is cos theta upon 1 cos theta?

Answer: The value of (1 + cos θ) / (1 – cos θ) is tan2 θ / ( sec θ – 1) 2.

## Is 1 cos theta sin theta?

The root of the equation 1 – cos theta = sin theta .

## How do you find the value of cos 1?

The value of cos 1 degrees can be calculated by constructing an angle of 1° with the x-axis, and then finding the coordinates of the corresponding point (0.9998, 0.0175) on the unit circle. The value of cos 1° is equal to the x-coordinate (0.9998). ∴ cos 1° = 0.9998.

## What is math theta?

Theta (uppercase Θ / lowercase θ), is a letter in the Greek alphabet. It represents the “th” sound (as in “think”) in Ancient and Modern Greek. … In mathematics, the lowercase θ is used as a variable to represent an angle, and the uppercase Θ is used in big-theta notation (a variant of big-O notation).

## Is cos theta equal to cos theta?

-cos (theta) is not equal to cos(-theta). As cos(-theta) is cos(theta) (even function). Also sin(-theta) is -sin(theta) (odd function).
