Formulae for Non-Right angle Triangle
Non-right angle triangle . triangle that is not a right triangle is an oblique triangle. Solving an oblique triangle means finding the measurements of all three angles and all three sides. Non right angle triangle
Applications of sine/ cosine rules.
Unit circle Worksheet
Unit circle plays an vital role in trigonometry. The unit circle provide values of T -ratios for given angles. Unit circle worksheet
Linear inequality
A System of Linear Inequalities is the set of two or more linear inequalities which are having same variables. The graph of an inequality in two variables is the set of points. Hence solution of inequalities is get by graph.Further we plot linear inequalities on graph. Therefore the overlap area will be solution of inequalities. Inequalities […]
Unit circle and trigonometric graph
Unit circle is the source for the generation of the trigonometric function graphs. The quadrants from the unit circle, when placed horizontally in numerical order, create the basis for the trigonometric graphs. Hence This process of creating graphs from the unit circle is often called “unwrapping” the unit circle. Unit circle with Trigo Graph
Sine Cosine and Area of triangle
Law of Cosines (also called the Cosine Rule) says: c2 = a2 + b2 − 2ab cos(C ). Law of Sines (or Sine Rule) is very useful for solving triangles: a sin A = b sin B = c … sine of angle B, and also equal to side c divided by the sine of […]
Algebraic Expansion
The Expansions of Algebraic Expression The formula: a(b+c) = ab + ac Algebraic Expansion. (a+b)(c+d)=ac+ad+bc+bd and (a+b)(a-b)= a ² – b² difference of square (a+b)² = a² + 2ab + b² perfect square (a-b) ²=a²-2ab+b² Expansion
Forms of Quadratic Equation
This post about forms of quadratic equations. In this post general quadratic equations with graph.This post is also include important facts quadratics like vertex , x-intercept and y-intercepts. The quadratic equation is an important topic in all syllabus like IB and cambridge etc A quadratic equation is an equation of the second degree, meaning it contains at […]
