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 […]
Transformation of Functions
In this post question are from transformation of functions. It basically deals with translation of functions through vector . Also it deal with reflection . transformation
Sequences and Series
Sequences and series is arrangement of term in particular pattern. Mathematical structures using the convergence properties of sequences. In particular, sequences are the basic for series sequence and series
Trigonometric Equation
Solving trig equations use both the reference angles and trigonometric identities The general method of solving an equation is to convert it into the form of one ratio only. Then, using these results, hence, we can obtain solutions. Trigonometric equation
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 […]
Exterior angle of Polygon
Exterior Angles of a Polygon add up to 360°. In other words the exterior angles add up to one full revolution. Exterior angle
Conversion of Co-ordinates
Convert from Polar to Cartesian. When we know a point in Polar Coordinates (r, θ), and we want it in Cartesian Coordinates (x,y) . we solve a right triangle with a known long side and angle: Answer: the point (13, 22.6°) is almost exactly (12, 5) in Cartesian Coordinates. Polar to cartesian
Complex Number
Conversion from Polar to Rectangular Form Complex and vice versa. r cos Θ = x , r sin Θ = y Conversion of polar to Rectangular
