Hi everyone! In this video
we're going to look at the math editor
here in Blackboard. So, once you have your
subject line typed in and you started
to type your message, you may want to
insert mathematical notation. To do that
click on fx button and that will
launch the math editor. Once the math
editor pops up, you will see several tabs
along the top of the screen. So, the first
tab here has several mathematical
operations like fraction or square root.
At the far right hand side you will
see notation related to Calculus. So
let's type in the definite integral.
Click on that button. We'll do the
definite integral from 0 to 1 and
Let's type in a fraction. Up in our
numerator, we will have the square root of
x and in the denominator will have 2.
So, we've got the integral from 0 to 1 of
the square root of x over 2 dx. Now, to
solve this by our constant multiple rule
we can pull out the 1/2 in front.
So let's do that. Let's put that fraction
one-half out in front and we're left
with just two square root dx for the
integrand. Well the square root of x is the
same as x to the one-half power so
let's put that in there
and we can now find the anti-derivative.
Try to keep everything lined up so we
have the anti-derivative (see that one
half is a constant so that is still out in
front) and the anti-derivative of x to
the one-half... that's going to be
two-thirds x to the three halves power.
O.k. Then, we need to plug in the
zero and one and proceed to solve
from there.
