Question #aa804 - Socratic
a). color (blue) ( {x in RR}) b). color (blue) ( {x in RR : 0 < x <=3}uu {x in RR : -3<= x < 0 }) c). color (blue) ( {x in RR : -4 <= x < sqrt (13)}) h (x) = (x-3)/ (x^2+9) x^2+9>0 for all real x, so domain is: color (blue) ( {x in RR}) g (x)= (sqrt (9-x^2))/x Since we have x in the denominator, x != 0 For real numbers: 9-x^2>= 0 9-x^2>= 0=x^2 ...
Question #2872d + Example - Socratic
A rank-m tensor is a mathematical object that represents N^m real numbers, where N is the dimension of space. rank-0 Tensor: represents a single real number and is usually called a scalar. Examples of rank-0 tensors (scalars) are temperature, density etc. rank-1 Tensor: represents N real numbers and is usually called vectors. Examples of rank-1 tensor (vector) are velocity, force, etc. rank-2 ...
Question #11ebf - Socratic
1 So we know that on the real numbers, sin and cos are bounded. This means that -1<=cos (x)<=1 and -1<=sin (x)<=1 AA x in RR So we can manipulate the limit to take advantage of this.
How do you solve the equation #2x^2-3x+1=0# by completing ... - Socratic
x=1" " or " "x=1/2 >f (x) = 2x^2-3x+1 The difference of squares identity can be written: a^2-b^2 = (a-b) (a+b) We will use this with a= (4x-3) and b=1. First pre ...
Question #b8278 - Socratic
Basically the same as we do with the real numbers. Perhaps if we rewrite this as: (3+2i)* (1-3i) then we mulitply 3 from the first paranthesis with the both constituents from the second. We do the same thing for the second constituent from the first paranthesis.
Question #5aa42 - Socratic
See explanation. Between any 2 real numbers there are infinitely many other numbers. To find such numbers you can do the following: Find the common denominator: 1/5=3/15; 1/3=5/15 The number between them is: 4/15
Question #4c938 - Socratic
Log of a negative number is undefined. There is no solution for this in real numbers. To solve it you would have to deal with complex numbers.

How do you simplify abs21? + Example - Socratic
|21|=21 |a| is called the absolute value or modulus of the number a. It represents the distance of the point from origin to its location on the real number line (if the number is real). As it is 'distance', it is always positive. For example absolute value of a negative number say -8 is written as |-8| and is equal to 8. It is apparent that absolute value of zero is zero and that of a positive ...
