Algebraic Methods Of Solving A Pair Of Linear EquationsSometimes, graphical method does not give an accurate answer. While reading the coordinates of a point on a graph paper, we are likely to make an error. So, we require some precise method to obtain a…

Simplifying Rational (Fractional) ExpressionsTo simplify an algebraic fraction means to reduce it to lowest terms. This is done by dividing out the common factors in the numerator and the denominator.Read more: Adding and Subtracting Rational (Fractional…

Domain, co-domain and range of functionIf a function f is defined from a set A to set B then for f : A ⟶ B set A is called the domain of function f and set B is called the co-domain of function f. The set of all f-images of the elements of A is called t…

What is meant by the Net of a Solid?NetsA net is a sort of skeleton – outline in 2-D, which, when folded results in a 3-D shape. OR A net of a 3-D figure is the shape that can be cut out of a flat piece of paper or cardboard and folded to make the 3D-sha…

Linear Equations In One Variable A statement of equality of two algebraic expressions, which involve one or more unknown quantities is known as an equation. A linear equation is an equation which involves linear polynomials. A value of the variable which…

Using Transformations to Investigate FunctionsLet’s investigate how transformations may be applied to functions:Example 1: Remember to utilize your graphing calculator to get a feel for the function and the changes. Transform the function f (x) = ex with…

CoFunctions Such examinations, lead us to three sets of “cofunction” identities: Also written: Notice the connection of the letters C & O: * sine and cosine cofunctions * tangent and cotangent cofunctions * secant and cosecant cofunctions * compleme…
