β 9y agoa + b = ab
a = ab - b = b(a - 1)
b = a / (a-1)
Any pair of numbers that satisfy that equation,
e.g. a = 3, b = 1½ . . . because 3 + 1½ = 4½ and 3 x 1½ = 4½
another example: a = 101, b = 1.01 because
101 + 1.01 = 102.01,
and 101 x 1.01 = 102.01

β 9y agoA star with a magnitude of +8 is "very dim", and not visible in urban or suburban areas. Only in the darkest rural areas, and only for people with EXCELLENT eyes, would a +8 magnitude star be visible.
Electrons have negative charge and protons have positive charge. These charges always have equal magnitude but opposite signs in an atom, maintaining electrical neutrality.
Speed is equal to the magnitude of velocity when the object is moving in a straight line without changing direction. In other words, if the velocity vector is pointing in the same direction as the motion of the object, then the speed will be equal to the magnitude of the velocity.
ab+ a+ b+
They are equal in magnitude and act in opposite directions.
a and b must face in opposite directions.
2pi/3 radian or equivalent 120 degree
If vector equation A + B = 0, it means that vector B is equal in magnitude but opposite in direction to vector A. Therefore, the magnitude of vector B is equal to the magnitude of vector A.
1. When the two vectors are parlell the magnitude of resultant vector R=A+B. 2. When the two vectors are having equal magnitude and they are antiparlell then R=A-A=0. For more information: thrinath_dadi@yahoo.com
b + a + b - a = 2b
if b + a , since a+b equals b + a due to it being commutative . it shud have the same magnitude and direction
2b
If a = 2b

The components of these vectors will be equal in magnitude but opposite in direction. This can be proved as follows.If A+B=0 then A=-BOr Axi+Ayj+Azk=-(Bxi+Byj+Bzk)Comparing the co-efficients of i, j, kAx=-Bx Ay=-By Az=-BzThis shows that components of A and B are equal in magnitude to each other but are opposite in direction.
If you do not assume that "plus" is commutative, all that can be said that it is equal to A plus B.
(a+b)(a+b)Also equal to a2+2ab+b2
