Mathematics is divided into various branches that have their importance. Among them, Trigonometry is one such vital branch of mathematics that studies the relationship between the angles of a right-angled triangle and its side lengths. Trigonometry emerged in the 3rd century BC, when the Greek mathematicians like Archimedes and Euclid studied the properties of the chord, calculated and geometrically presented them to prove theorems that are identical to modern trigonometric formulas. Hipparchus of Nicaea is considered the father of Trigonometry and has been given the credit for compiling the first trigonometric table. Basically, Trigonometry is defined with six main ratios, namely Sine(sin), Cosine(cos), Tangent(tan), Cosecant(cosec), Secant(sec) and Cotangent(cot). (image will be uploaded soon) In the above-given picture of a right-angled triangle, the longest side is known as hypotenuse. The other two opposite sides of the hypotenuse are called adjacent and opposite. The angle between the adjacent and opposite is 90°. The important trigonometric formula for class 11 are as follows: 1. sin A = opposite/ hypotenuse = a/ c 2. cos A = adjacent/ hypotenuse = b/ c 3. tan A = opposite/ adjacent = a/ b = ( a/c)/( b/c) = sin A/ cos A 4. cosec A = 1/ sin A = hypotenuse/ opposite = c/ a 5. sec A = 1/ cos A = hypotenuse/ adjacent = c/ b 6. cot A = 1/ tan A = adjacent/ opposite = cos A/ sin A = b/ a Below given is the list of special trigonometry formulas for class 11.

Reciprocal Identities: $cosec(x) = \frac $ |cos x|=1, general solution is given by $x=n \pi$ Some basics Tips to solve the trigonometry questions (1) Always try to bring the multiple angles to single angles using the basic formula. Make sure all your angles are the same. Using $sin(2x)$ and $sin(x)$ is difficult, but if you use $sin(2x) = 2 sin(x)cos(x)$, that leaves $sin(x)$ and $cos(x)$, and now all your functions match. The same goes for addition and subtraction: don’t try working with $sin(x+y)$ and $sin (x-y)$. Instead, use $sin(X+Y) = sin(x)cos(y)+cos(x)sin(y)$ so that all the angles match (2) Converting to sin and cos all the items in the problem using a basic formula. I have mentioned sin and cos as they are easy to solve. You can use any other also. (3)Check all the angles for sums and differences and use the appropriate identities to remove them. (4) Use Pythagorean identifies to simplify the equations (5) Practice and Practice. You will soon start figuring out the equation and their symmetry to resolve them fast Download all the trigonometry Formulas below Hope you like this compilation of Trigonometry Formulas for class 11.

Trigonometry Table Trigonometry Table 0 to 360: Trigonometry is a branch in Mathematics, which involves the study of the relationship involving the length and angles of a triangle. It is generally associated with a right-angled triangle, where one of the angles is always 90 degrees. It has a vast number of applications in other fields of Mathematics. Many geometric calculations can be easily figured out using the table of Trigonometric ratios table helps to find the values of trigonometric standard angles such as 0°, 30°, 45°, 60° and 90°. It consists of trigonometric ratios – sine, cosine, tangent, cosecant, secant, cotangent. These ratios can be written in short as sin, cos, tan, cosec, sec and cot. The values of trigonometric ratios of standard angles are essential to solve the trigonometry problems. Therefore, it is necessary to remember the values of the trigonometric ratios of these standard angles. The trigonometric table is useful in the number of areas. It is essential for navigation, science and engineering. This table was effectively used in the pre-digital era, even before the existence of pocket calculators. Further, the table led to the development of the first mechanical computing devices. Another important application of trigonometric tables is the Fast Fourier Transform (FFT) algorithms.
