If we have n number of variables and n-1 equations the we will have to solve in terms of one variable. For n-2 equations, in terms of two variables etc. From example we have #n=3# variables and #3-1# …

Range: Any real number of #y# except #y=0# Range: #y in RR | y !=0#.In interval notation expressed as #y| (-oo,0)uu (0,oo)# graph {1/ (x^2-2) [-10, 10, -5, 5]} [Ans] Answer link You can reuse this answer

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 …

Make a vector, veca, from p_1 to p_3 : veca = (3-2)hati+(a-3)hatj+(3-2)hatk Simplify: veca = hati+(a-3)hatj+hatk Make a vector, vecb, from p_2 to p_4: vecb = (4-3)hati+(2-4)hatj+(a-0)hatk Simplify: vecb …

These values can be 2;3 and 4. To solve this inequality you have to: substract 7 from both sides to leave -x on the left side. multiply (or divide) both sides by -1 and change the inequality sign to get rid of - …

#k (x) = x^3 -4x^2 -7x +10# is one solution. (You can check if it is correct by actually plugging in the numbers -2, 1, or 5!) You could have infinitely many other solutions by multiplying k (x) by some real …

If z_1 and z_2 have same arguement then we can say z_2=kz_1, where k is a real number. As a=z_1+z_2= (k+1)z_1, argz_1=argz_2=arga and as b=z_1*z_2, argb=argz_1+argz_2=2arga As …

This inequality is true for every real number x. Left side of this inequality is absolute value, which is always greater than or equal to zero, therfore also greater than -4 no matter what the value of x is.

Make the sum epsilon + delta less than or equal to the distance between a and b, which is abs(a-b)
