Logarithmic Expressions are simplify by Rules or Laws of Logarithms and solve by inverse of exponentiation. It is expressed by using the abbreviation “log”. Because of different base of number log notation are also different. lg for base 10 , ln for base e . Logarithm quotient rule The logarithm of the division of x and y is the difference of logarithm of x […]

Binomial Theorem
Binomial theorems is another ways of expansion of two terms. Another way it is generalised form of expansion. Due to expansion of two term it is binomial. “What are the binomial coefficients?” . It shows how to calculate the coefficients in the expansion of (a + b) n. The symbol for a binomial coefficient nCr. As well as pascal […]
Absolute Equation
Solving absolute value equations and inequalities. And represents the distance between a and 0 on a number line. An absolute value equation is an equation that contains an absolute value expression. Has two solutions x = a and x = -a because both numbers are at the distance a from 0. Absolute Equation
Imaginary No.
Complex numbers have two parts, a “real” part and an “imaginary” part (being any number with an “i” in it). The Complex numbers is ” a + bi “; that is, real-part first and part imaginary i=√(-1) due to presence to i second part is imaginary. Imaginary no
Product to Sum
Product‐Sum and Sum‐Product Identities. The process of converting products into sums can make a difference . Integrate \( \int \! \sin 3x \cos 4x \, \mathrm{d}x.\) This problem may seem tough at first, but after using the product-to-sum trigonometric formula, this integral very quickly changes into a standard form . Converting a sum of trig functions into a product. Write as and then […]
Conversion Complex No Rectangular to Pol...
Converting from Polar Form to Rectangular Form. Either method of notation is valid for complex numbers. Rectangular form lending itself to addition and subtraction, and polar form lending itself to multiplication and division. Hence polar form of a complex number is another way to represent a complex number. The form z = a + b i is called the rectangular coordinate form of a complex number. This representation is very useful when we multiply or divide complex numbers. Therefore argand diagram use […]
Integration by trigonometric substitutio...
This post is about worksheet of Integration by trigonometric substitution. It also one of most important concept of integral calculus . The function ƒ(φ(t))φ′(t) is also integrable on [a,b] Integration by substitution
Volume -2
To get a solids of revolution we start out with a function, y=f (x), on an interval [a,b]. We then rotate this curve about a given axis to get the surface of the solid of revolution. Volume
