Cos 60 value

Cos 60 Degrees In trigonometry, Sine, Cosine and Tangent are the three major or primary ratios, which are used to find the angles and length of the sides of the triangle. Before determining Cos 60 degrees whose value is equal to 1/2, let us know the importance of Cosine function defines a relation between the adjacent side and the hypotenuse of a right triangle with respect to the angle formed between the adjacent side and the hypotenuse. In other words, the Cosine of angle α is equal to the ratio of the adjacent side (also called as a base) and hypotenuse of a Also, find a few important values of other trigonometric ratios: • • • • Cos 30 degrees • • The trigonometric functions, sin, cos and tan for an angle are the primary functions. The value for cos 60 degrees and other trigonometry ratios for all the degrees 0°, 30°, 45°, 90°, 180° are generally used in trigonometry equations. These trigonometric values are easy to memorize with the help Cos 60 Degree Value In a right-angled triangle, the cosine of ∠α is a ratio of the length of the adjacent side (base) to the ∠α and its hypotenuse, where ∠α is the angle formed between the adjacent side and the hypotenuse. Cosine α = Adjacent Side / Hypotenuse Cos α = AC / AB Cos α = b / h Now, to find the value of cos 60 degrees, let us consider, an Here, AB = BC = AC and AD is perpendicular bisecting BC into two equal parts. As we know, cos B = BD/AB Let us consider the length of each side as 2 units, such as AB ...

Trigonometry is useful for studying the measurements of the right-angled triangles which deal with the parameters like height, length, and angles of a triangle. It has a variety of applications in the real world as well. Apart from Mathematics, it has a huge range of applications in several other fields like engineering, medical imaging, satellite navigation, architecture, development of sound waves, etc. Some applications make use of the wave pattern of the Trigonometry is a branch of Mathematics dealing with the right-angled triangles. This concept was initiated by the Greek Mathematician Hipparchus. It is further divided into plane Trigonometry and spherical Trigonometry. The cosine function in Trigonometry is used to find out adjacent sides or hypotenuses. Applications of Trigonometry: • Trigonometry is used in oceanography, meteorology, seismology, astronomy, physical sciences etc., • It is also used to find out the height of tall structures and geographical features, length of a long river, upstream and downstream distance. • It is used by the aviation industry to measure the speed, direction of the wind to control and fly aircraft and planes • It is used by archeologists when they excavate new layers of civilization with minimal damage to the area. • Trigonometry is used in criminology to measure the collision of objects like cars etc., to understand the case study further. This will help in unveiling the clues further. • It is also used to erect walls parallel and ...

Pythagoras x 2 + y 2 = 1 2 But 1 2 is just 1, so: x 2 + y 2 = 1 equation of the unit circle Also, since x=cos and y=sin, we get: (cos(θ)) 2 + (sin(θ)) 2 = 1 a useful "identity" Important Angles: 30 °, 45 ° and 60 ° You should try to remember sin, cos and tan for the angles 30 °, 45 ° and 60 ° . Yes, yes, it is a pain to have to remember things, but it will make life easier when you know them, not just in exams, but other times when you need to do quick estimates, etc. These are the values you should remember! How To Remember? To help you remember, cos goes "3,2,1" cos(30 °) = √ 3 2 cos(45 °) = √ 2 2 cos(60 °) = √ 1 2 = 1 2 And, sin goes "1,2,3" : sin(30 °) = √ 1 2 = 1 2 (because √1 = 1) sin(45 °) = √ 2 2 sin(60 °) = √ 3 2 Just 3 Numbers In fact, knowing 3 numbers is enough: 1 2, √2 2 and √3 2 Because they work for both cos and sin: Your hand can help you remember: For example there are 3 fingers above 30°, so cos(30°) = √ 3 2 What about tan? Well, tan = sin/cos, so we can calculate it like this: tan(30°) = sin(30°) cos(30°) = 1/2 √3/2 = 1 √3 = √3 3 * tan(45°) = sin(45°) cos(45°) = √2/2 √2/2 = 1 tan(60°) = sin(60°) cos(60°) = √3/2 1/2 = √3 * Note: writing 1 √3 may cost you marks so use √3 3 instead (see Quick Sketch Another way to help you remember 30° and 60° is to make a quick sketch: Draw atriangle with side lengths of 2 Cut in half.
