Trigonometric ratio
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. Trigonometric ratio
Multiple angle identity
Multiple angles identity are nothing but the trigonometric identity of multiple angles. Use for Proof of the double-angle and half-angle formulas. Solving Trigonometric Equations and Identities using Double–Angle and Half- Angle Formulas, examples and step by step solutions. Hence double angle formulae for sin 2A, cos 2A and tan 2A use for solving identity. Also to solve […]
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 […]
circular measure
The radian is a unit of measurement angle . Therefore, this unit is used in many topics likewise sector , angles . Parts of the mathematics area which include circular measure and more often, the branch of angle measurements where pi (Π) is used. Therefore, radian use to measure arc length, chord length, area of sectors of a circle and many others. […]
Sine and Cosine Rule
the Sine Rule to find unknown sides and angles; Use the Cosine Rule to find unknown sides and angles. Sine and Cosine rule
Trigonometric Identity
Trigonometric identities showing that the identity is always true, no matter what value of x or θ is used. Because it has to hold true for all values of x, we cannot simply substitute in a few values of x to “show” that they are equal. We have to use logical steps to show that one […]
Graph of Trigo function
Trigo functions definition is – a function of an arc or angle most simply expressed in terms of the ratios of pairs of sides of a right-angled triangle —called also circular function. standard unit circle (a circle with radius 1 unit), starting at the origin and making some angle with the x -axis, the sine of the angle gives the […]
