The roots of the quadratic function y = 1 / 2 x 2 − 3x + 5 / 2 are the places where the graph intersects the x-axis, the values x = 1 and x = 5. They can be found via the quadratic formula. In elementary algebra, the quadratic formula is a closed-form expression describing the solutions of a quadratic equation.
Ptolemy's theorem states that the sum of the products of the lengths of opposite sides is equal to the product of the lengths of the diagonals. When those side-lengths are expressed in terms of the sin and cos values shown in the figure above, this yields the angle sum trigonometric identity for sine: sin( α + β ) = sin α cos β + cos α sin ...
Simplification is the process of replacing a mathematical expression by an equivalent one that is simpler (usually shorter), according to a well-founded ordering. Examples include:
For example, it could call for $500 billion in increased revenues over the coming 10 years, and tell lawmakers on the tax-writing committees to write a bill that would raise taxes by that amount ...
Robert F. Kennedy Jr.'s personal attorney previously lobbied the Food and Drug Administration to revoke its approval of the polio vaccine, highlighting an influential Kennedy ally who, sources ...
(Reuters) -Archer Aviation said on Thursday a joint venture between Japan Airlines and Sumitomo Corp had secured the right to place orders for up to 100 of its electric air-taxis worth $500 million.
For example, 3x 2 − 2xy + c is an algebraic expression. Since taking the square root is the same as raising to the power 1 / 2 , the following is also an algebraic expression: + See also: Algebraic equation and Algebraic closure
$2.97 . While the majority of the white bread brands I tried were extremely similar, the top two sit in a major league of their own. Nature’s Own is a completely different experience than the ...
