How do you type root on the keyboard?
[r][o][o][t] where [x] means press the button marked with x.
What is x and what is o?
X is hugs because your arms cross to make an X, and O is kisses cause your lips make an O. (:
What does X equal for the equation negative sin x minus cos x equals 0?
Consider the meaning of the sine and cosine functions. They are ratios of the side lengths in a right triangle. Sine is the length of the side opposite the angle, divided by that of the hypotenuse, and cosine is the length of the adjacent side, again, divided by the length of the hypotenuse. Consider then: sin = o/h cos = a/h This means that according to our problem, if x is the angle we're measuring in the triangle: -(o / h) - (a / h) = 0 ∴ -o - a = 0 ∴ a = -o Which tells us that the opposite and adjacent sides on our triangle are of equal length. This means that our triangle is not only a right triangle, but an isosceles triangle as well. That means that our angle (x) must be π/4, or 45°
What is law of integers?
There is not a single law. Integers form a Group and this means that they form a set of elements (numbers) with a binary operation (addition) which satisfies the following four properties for any three integers, x y and z:x and y belong to Z => x + y belongs to Z (closure),(x + y) + z = x + (y + z) {associativity)there is an element, o, in Z, such that x + o = x = o + x (identity). o is represented by the number 0.for every x in Z, there is an integer x' such that x + x' =0 = x' + x (additive inverse). x' is denoted by -x.Furthermore, the Group is Abelian:x + y = y + x (commutative).The set also has a second operation defined on it: multiplication. which is distributive over addition:X *(y + z) = x * y + x * z.
Which letter has rotational symmentry?
I, l, o, O, S, s, X, x, Z, z
