Linear Algebra Chapter 2 Solving Linear Equations 笔记 不翻筋斗去取经 make God laugh (人类一思考,上帝就发笑)Gilbert Strang : 这一章将会解n个未知数的n个方程组,我不会讲得很快,因为smaller systems allow examples and pictures and a complete understanding. 你可以自由地往前学,只要你觉得 matrix mult...

We can solve equations in which a variable is raised to a rational exponent by raising both sides of the equation to the reciprocal of the exponent. The reason we raise the equation to the reciprocal of the exponent is because we want to eliminate the exponent on the variable term, and ...
Equations in quadratic form are equations with three terms. The first term has a power other than 2. The middle term has an exponent that is one-half the exponent of the leading term. The third term is a constant. We can solve equations in this form as if they were quadratic. A few...

Equations will often involve algebra and contain unknowns (variables) which we often represent with letters such as x or y. We can solve simple equations and more complicated equations to work out the value of these unknowns; they could involve fractions, decimals or integers. Step-by-step ...
Equivalent Equations Posted onOctober 15, 2011byPassy Image Source: http://static.guim.co.uk The above containers are not all equal, but they are “Equivalent”. They are “equivalent”, because they all contain milk ! In Algebra, we can have “Equivalent” Equations, that look different in...
