Substitution method

 “I hope that you all had an incredible time with your families yesterday on the Thanks given day.” Today going back to my notes I was reviewing one of the problems that deal with substitution, I worked this problem at the Success Center couple days ago. This problem was for math 120 and this type of problem is quite similar to those in Calculus 220. Is surprising that they require the same process to get to the answer and how the substitution is helping us to achieve the goal that we are after.

Here is the pic. Of this quadratic that involves negative exponents.

Many month ago while watching my favorite program of BBC TV, I encounter one program in particular that caught my attention. The video is title Beautiful Equations and it talks about some of the most difficult equation to understand. Those equations are so complicated and interesting, and I know that later in my career I will deal with them. Hopefully I will be able to comprehend them.

The equation that really thrills me is one from relativity theory that involves time, just to be able to apply it and prove it, it’s quite a challenge. So I truly recommend surfing videos over YouTube and watching some of the BBC and Beautiful Equations in particular.

Hi everyone,
