The integration of a periodic function involves some unique properties and approaches due to the function’s repeating nature. A function $f(x)$ is said to be periodic with period $T$ if for all $x$ in the domain of $f$, $f(x + T) = f(x)$. This periodicity can significantly simplify the integration process over intervals that are […]

Glossary of Mirror and Lenses
Plane Mirror
A plane mirror is a mirror with a planar reflective surface. For light rays striking a plane mirror, the angle of reflection equals the angle of incidence.It always form virtual image
Concave or Converging Mirrors
A curved mirror that has its center farther away from you than its edges is called a concave mirror. A concave mirror tends to reflect parallel rays through a point called its focus – in other words a concave mirror converges light. Therefore concave mirrors are often referred to as converging mirrors. This converging effect makes sense if you imagine a concave mirror to be an array of small plane mirrors.You can demonstrate the converging of parallel light rays by a concave mirror quite dramatically for yourself. A relatively small concave mirror placed in the sun will gather enough light to ignite a small piece of paper quite quickly

The integration of sin cube x $\sin ^3 x$, can be found using integration substitution and trigonometry identities . The integral of $\sin ^3 x$ with respect to (x) is: \[\int \sin^3 x \, dx =\frac {\cos 3x}{12} – \frac {3\cos x}{4} + C\] or \[\int \sin^3 x \, dx =+\frac{\cos^3(x)}{3} – \cos(x) + C\]

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 =)
to take down key poin

Integration is a fundamental concept in calculus, often seen as the inverse operation of differentiation. There are several key rules and techniques for integration, each useful in different situations. Here’s an overview of the most important ones: Basic Integration Rules Integration of Trigonometric Functions Exponential and Logarithmic Functions Integration by Substitution Used when an integral
1. Find a place where you go only to study. It should be quiet area .Identify your distractions. Find ways to decrease them or to postpone them until study breaks e.g., taking the phone off the hook, turning off Whatapps. If using a computer, exit out of email and messengers.
2. Always sit straight in a chair at a desk, start out with questions about the material, outline chapters, underline key phrases after reading section, write notes in margins, ask yourself what you have learned.Take good notes of the chapter and revise them also.If you have difficulty understanding any thing ,search it in other books and internet. If it is not resolved,write it down to discuss with Friends and teacher
3) Doing a big task may seems to be impossible to you. So Divide your work into smaller manageable tasks that can be completed in a short period of time. First Push yourself to complete one small task, then move on to the next task. Focus on one small task at a time.

1) Find a good study spot .A place with a lot of distractions makes for a poor study area.A quiet place with no distraction would be good study place.
2) Take good Notes. Read through your materials slowly and write down key points. Write down any questions you have about the materials that you can later discuss with your classmates or course instructor.Quiz yourself on the material you have just read. If you struggle with certain questions, make not of these areas for additional study.Summarize the Main Points .Once you have studied the material, see if you can answer these questions: Can you identify the main concepts covere
