Answer:
Step-by-step explanation:
Let's use the definition of the Laplace transform and the identity given: with .
Now, . Using integration by parts with u=e^(-st) and dv=cos(5t), we obtain that .
Using integration by parts again with u=e^(-st) and dv=sin(5t), we obtain that
.
Solving for F(s) on the last equation, , then the Laplace transform we were searching is
-2 is the correct answer.
Answer:
130,000 to 250,000
Step-by-step explanation:
Answer:
U ={ Parallelograms}
A= { Parallelogram with four congruent sides}={ Rhombus,Square}
B ={ Parallelograms with four congruent angles} ={ Rectangle, Square}
So, AB= { Square}
So among all the parallelograms "Square" is the only parallelogram which has all congruent sides as well as all congruent angles.
