U Substitution e^(x) | Every Step Calculus
Raw Transcript
Hello Tom from every step
Calculus dot com. Here’s a problem on u-substitution.
L,et’s get started index8() to go to my menu.
u-substitution is the subject.
Press alpha before you enterr anything in these entry lines here.
Diamond key to get to the
e(x) problems this is 7 times
X. Divided by.
Anytime you using the denominator you always have to have parentheses
around the whole function.
And then we’re going to go
to e(x) again. 7
times X plus
8.
I always show you what you’ve entered, you can change it if you want, I say it’s okay.
You have to rewrite this. Notice the idea is that the seven ex/dx is the same as
here. Otherwise it’s not a u-substitution problem.
And then I check whether that’s that’s true.
So they’re equal so we say yes.
And here’s the answer 7 times log e to the x
plus c. Pretty neat huh? Every Step Calculus dot com, go to my site buy my programs
