Trigonometric Integrals

Integration of Sine and Cosine Powers In the reduction formulas section, we obtain the formulas: In the case where n = 2, these formulas are: Alternative forms for these integration formulas can be obtained using trigonometric identities. that come from the double-angle formulas These identities give rise to the integration of sine and cosine products. If m and n are positive integers, then the integral can be calculated in a number of ways, depending on whether m and n are odd or even.

Three simple rule

Simple three rule is a practical process for solving problems involving four values ​​of which we know three of them. We must therefore determine a value from the three already known. Steps used in a simple three rule 1) Construct a table by grouping the quantities of the same species into columns and keeping the quantities of different species in correspondence in the same row.

Goldbach conjecture

In mathematics, a conjecture is a proposition that many mathematicians believe to be true, based on assumptions, evidence, forebodings, hypotheses, but have not yet proved it. Goldbach's famous conjecture is one of the oldest unresolved problems in mathematics. It was proposed on June 7, 1742 by Prussian mathematician Christian Goldbach, in a letter written to Leonhard Euler.

Tips for Calculations (Part 3)

TIP 12: Times tables of 9 If you have difficulty decorating the times table of 9, you can do the following: 1) Consider the number before which you will multiply by 9. 2) See how much it is left to reach 9. 3) Join the two numbers found. For example: 1) 9 x 2 => the number before two is 1.

Niels Henrik Abel

Niels Henrik Abel was born on August 5, 1802 in Finnoy, Norway, and died on April 16, 1829 in Froland, Norway. He proved the impossibility of algebraically solving the general fifth degree equation. Abel's life was dominated by poverty. After the death of his father, who was a Protestant minister in 1820, Abel had a responsibility to support his mother and family.
