I suggest that it is (sin A)^2 + (cos A)^2 = 1
An identity is like an equation which is true for all values of the variable.

The main kinds are plane trigonometry and solid trigonometry. The latter will include trigonometry in hyper-spaces.
Hipparchus is the father of trigonometry.
Trigonometry based on a unit circle and radians and trigonometry based on a right triangle.
An identity is like an equation which is true for all values of the variable.
Trigonometric identities are trigonometric equations that are always true.
Yes, lands have color identity in Magic: The Gathering. This means that a land's color identity is determined by the colors of mana it can produce, which can affect deck-building strategies and card interactions.
No, lands do not have a color identity in Magic: The Gathering. They are considered colorless unless they have specific abilities or characteristics that give them a color.

In Magic: The Gathering, the commander color identity is determined by the colors of mana symbols in the card's mana cost and rules text. The commander's color identity includes all colors in its mana cost and any color symbols in its rules text.
The main kinds are plane trigonometry and solid trigonometry. The latter will include trigonometry in hyper-spaces.
csc(x) = 1/sin(x) = +/- 1/sqrt(1-cos^2(x))
Hipparchus is the father of trigonometry.
It is a number - in trigonometry or elsewhere.
TRIGONOMETRY
Trigonometry is applied in construction and building, as trigonometry measures right angled triangles.
