Vertex of a parabola is at the ‘origin’ and the axis of symmetry is along the x or y-axis, then the equation of the parabola is the simplest. So that its vertex is (h,k) and its axis of symmetry is parallel to the x-axis, it has an equation of (y – k)2= 4p (x – […]

Transformation of function
Graph transformation is the process by which an existing graph. Transformation is four types . Transformations of Graphs … For the base function f (x) and a constant k, the function given by. g (x) = f (x) + k;. can be sketched by shifting f (x) k units vertically. similarly g(x) = kf(x) , […]
Volume and surface area of solid
Surface area and Volume help us measure the size of 3D objects. We’ll start with the volume and surface area of rectangular prisms. Volume and surface area
Co-ordinate geometry-2
Plot ordered pairs on a coordinate plane. The axes divide the plane into four quadrants. A point in a coordinate plane is named by its ordered pair of the form of (x, y). The first number corresponds to the x-coordinates and the second to the y-coordinate. Similarly we can identify coordinate point from graph. Also […]
Interpretation of trigonometric graph
Sound waves travel in a repeating wave pattern. This represent graphically by sine and cosine functions. As trigonometric function is periodic therefore it use for sound wave. Similarly we use in wheel also for model function, because of rotation of wheel. Also use of periodic conditions. trigonometric function
Angle unit conversion
Radians and degrees are two different units for angle. The radian is the SI unit for measuring angles. Because it is continuous therefore it is use in trigonometric function. Hence it represent in multiple of π. Angle unit conversion
Trigonometric Equation(Degree)
Trigonometric Equations involve one or more trigonometric ratios of unknown angles. Due to difference unit of angle , hence it gives angle in two different form. Similarly it give value in degree. Trigonometric Equation
Trigonometric identity
Trig identity is equations that are true for Right Angled Triangles. D1: sin 2A+ cos 2A=1 D2: 1+ tan 2A= sec 2A D3: 1+ cot 2A= csc 2A Hence trigonometric identities are prove by above D1,D2 and D3. Similarly also using reciprocal identity. Trigonometric Identity
Trigonometric ratio-2
The ratios of the sides of a right triangle are called trigonometric ratios. Sine, Cosine and Tangent are main ratio while rest three reciprocal. Hence Sine and Cosine are the trigonometric ratios, whose values are less that 1 for an acute angle. Because they are periodic. www.kutasoftware.com
