integration of sin7x

The integration of $sin^7x$, can be found using integration substitution and trigonometry identities . The integral of $\sin^7 x $ with respect to (x) is: \[\int \sin^7 x \, dx =\frac{\cos^7(x)}{7} – \frac{3\cos^5(x)}{5} + \cos^3(x) – \cos(x) + C\] Here, (C) represents the constant of integration, which is added because the process of integration determines […]

Atwood machine

The Atwood machine (or Atwood’s machine) was invented in 1784 by Rev. George Atwood as a laboratory experiment to verify the mechanical laws of motion with constant acceleration. Atwood’s machine is a common classroom demonstration used to illustrate principles of classical mechanics.
The ideal Atwood Machine consists of two objects of mass m1 and m2, connected by an inextensible massless string over an ideal massless pulley.

Tips to take good notes in the class

Good note taking is one of the important steps to success in Exam’s.Good notes capture the most important facts and enable you to understand how every fact

fits into a larger puzzle.Here are some of the tips

1) Don’t write the each word of the teacher.Summarize your notes in your own words, not the instructor’s.

2)Take down key words and concepts, not sentences.Develop your own system of abbreviations or symbols (such as w/ for “with” or math symbols such as > or =)
