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

Trigonometric Equation (Radian)
Trigonometric Equation involve one or more trigonometric ratios of unknown angles. Due to difference unit of angle , hence it gives angle in different form. Similarly it give value in radian. Trigonometric equation
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

Tangent and normal : Implicit
Tangent and Normal Lines for implicit curves are a line that touches the implicit curve at one point and has the same slope as the curve at that point. A normal to a curve is a line perpendicular to a tangent to the curve. tangent and normal
Trigonometric Graph
Graphs of Trigonometric Functions. Below are the graphs of the six trigonometric functions: sine, cosine, tangent, cosecant, secant, and cotangent. Explore the amplitude, period, and phase shift by examining the graphs of various trigonometric functions. Graph of y = sin x. Graph of y = sin ax. Graph of y = cos x. Graph of y […]
Approximating area under the curve
Approximate area of under a curve. Compute left, right, and midpoint Hence Riemann sums use with n rectangles are computed. Due to the this it approximate area. Approximate area under
Vectors and scalar product
Scalar product of two vectors is multiply and obtain a scalar quantity. It represent on ‘dot’. Another name is dot product. vector has magnitude and direction. It start from one point to another point. The length of vector is called magnitude. Scalar product and vector
