where i^ and j^ represent the components of a vector in the x and y direction. This is the exact same thing and carries the same meaning; it's just often written in this notation. The vector previously discussed
In unit-vector notation, what is the sum of A = (5.4m)i + (1.4m)j and B = (-14.0m)i + (6.4m)j? What are the magnitude and the direction of A + B (relative to i)? A vector A has a magnitude of 6 units and it has a direction along a vector B= -3i-2j-5k. Write...

This seems to be the main focus of Khan's rebuttal of my critique - but he missed the bigger problems. The other issue he addresses is that I say this is a 1-D kinematics problem and doesn't require vector notation. That is correct - but if you want to call a scalar value a 1D...
In the realm of machine learning (ML), a knowledge graph is a graphical representation that captures the connections between different entities. It consists of nodes, which represent entities or concepts, and edges, which represent the relationships between those entities. Google coined the term know...

What is a vector? Why is 3(x - 3) not a monomial? What are functions in mathematics? What is the difference between a proposition and a statement? What is the meaning of regression in Mathematics? How would you define the term 'color line'?
In a typical NoSQL architecture, data access is managed by a software driver. Libraries in multiple languages are available to the database clients, allowing them toaccess the database. Even if these drivers are not vulnerable, they may have insecure APIs. This is another threat vector that ...
Find a direction vector for a line which is perpendicular to 3x +7y-21=0 What is a vector? Write the equation of the parabola x=-y^2 + 2y - 6 in standard form. Find the scalar equation of the line perpendicular to 3x -y+7=0 passing through (2,-3). ...
