Integration by U-substitution
Integration by U-substitution method When the integrand is formed by a product (or a division, which we can treat like a product) it's recommended the use of the method known as integration by u-substitution, that consists in applying the following formula: Even though it's a simple formula, it has to be applied correctly. Let's see a few tips on how to apply it well: 1. Select u and dv correctly: as a rule, we will call u all powers and logarithms; and dv exponentials, fractions and...

Logarithmic Equations and Systems
Logarithmic Equations and Systems A logarithmic equation is an equation that has an unknown factor in the argument of a logarithm. In reality, the resolution is reduced to the resolution of equations of the same type as the expressions in the arguments (quadratic equations, cubic equations, irrational equations...). Before starting the exercises, let's remember the logarithmic properties: Logarithm of a product: Logarithm of a quotient: Logarithm of a power: Change of base: Use...

Pythagorean Theorem
Pythagoren Theorem Pythagoras' Theorem: Given a right triangle with sides a and b and a hypotenuse h (the side opposite the right angle). Then, Remember that... triangle is a right-angled triangle because it has a right angle, an angle of 90º or π / 2 radians The hypotenuse is the opposite side as the right angle. Note: h is always bigger than the other sides, as shows h > a and h > b. The Pythagoras theorem is one of the most known results in mathematics and also one...

Exponential Equations
Exponential Equations An exponential equation is one that has exponential expressions, in other words, powers that have in their exponent expressions with the unknown factor x. For example: We will resolve some exponential equations without using logarithms. This method of resolution consists in reaching an equality of the exponentials with the same base in order to equal the exponents. Examples Example 1: Taking into account that we can write 16 as a power we can rewrite the equ...
