I honestly don’t ike to listen to music before or during a test. It just prevents me from thinking or staying focused. However, I love listening to music when I am doing the dishes, cleaning, stuff like that. The song Memories by Maroon 5 really calms me down. Here’s the link to it. https://youtu.be/SlPhMPnQ58k

Floyd Williams is an Emeritus Professor of Mathematics at the University of Massachusetts at Amherst. He is from Kansas City, Missouri. Floyd wanted  to understand Einstein’s theory of relativity and therefore became interested in math and chose to become a mathematics professor. Floyd has about a  100 published works, books included. He has been invited to lectures in about 24 states and 23 countries around the world. Floyd helped about 10 students to obtain their PHD. He was also inducted into the Lincoln University (Jefferson City, MO) Hall of Fame in 2011. What makes Floyd interesting to me is his passion for physics. I enjoyed learning in both physics 1 and 2 and found some of Einstein and Newton theories amazing. Floyd Williams is not involved in the black math community . 

this example is a integration by parts problem.

∫udv= uv- ∫vdu. ( use the integration by parts formula)

2∫xcos 5x

u = x. du = 1dx. dv =cos(5x). v = ∫cos(5x)dx

sin (5x) 5 dx = 1/5 sin (5x)

1/5 x sin(5x) – ∫ 1/5 sin(5x) 1 dx

1/5x sin(5x) – 1/5 ∫sin(5x) dx

1/5 x sin(5x)- 1/5.(1/5) cos (5x) this is what u get by integrating ∫sin(5x)

2 ( 1/5 x sin(5x) +1/25 cos (5x) +C

2/5 x sin(5x) +2/25 cos (5x) +C. final answer.
