To find the distances and heights we can use the mathematical techniques, which come under the Trigonometry. It shows the relationship between the sides and the angles of the triangle. Generally, it is used in the case of a right angle triangle.

Trigonometric Ratios

Right angle triangle In a right angle triangle, the ratio of its side and the acute angles is the trigonometric ratios of the angles.

In this right angle triangle ∠B = 90°. If we take ∠A as acute angle then -

AB is the base, as the side adjacent to the acute angle.

BC is the perpendicular, as the side opposite to the acute angle.

Ac is the hypotenuse, as the side opposite to the right angle.

Trigonometric ratios with respect to ∠A


                      

sin (90° – A) = cos A,
cos (90° – A) = sin A,
tan (90° – A) = cot A,
cot (90° – A) = tan A,
sec (90° – A) = cosec A,
cosec (90° – A) = sec A

Meteorological Data Analysis

Is there any change due in weather to global warming in of Finland by using Data analytics Effect of global warming “Has the Apparent temperature and humidity compared monthly across 10 years of the data indicate an increase due to Global warming” To find whether the average Apparent temperature for the month of a month say April starting from 2006 to 2016 and the average humidity for the same period have increased or not. step-1 Importing of libraries and Dataset. import libraries step-2 over Look at the dataset. step-3 Cleaning the Dataset step-4 Plotting a graph of the following Dataset > Firstly plot the graph whole dataset for all months Graph for all month > Now plot graph for a specific month(April) . Graph for month of April Conclusion: As we can analyze there isn’t any change in humidity in past 10 years( 2006–2016) for the month of April. where as , temperature increases sharply in 2009 and drops in 2015 for rest

Mechanical and durability Behavior of fiber reinforced concrete incorporating deferent types of natural, pp and steel fibers

1. Introduction As an important building material, concrete has been widely used in civil engineering applications such as bridges and roads engineering, and the related experimental study of the mechanical properties of concrete was also fruitful . With the vigorous development of engineering construction, high-performance concretes such as fiber-reinforced concrete was applied gradually in important engineering structures . Among these high-performance concretes, for the advantages of low cost, easy fabrication, and performance improvements, obviously, steel fiber-reinforced concrete was used widely in the current engineering field . However, the study showed that uneven incorporation of steel fiber would affect the fluidity and uniformity of concrete mixing and even result in fiber bonding, which eventually affects the reinforcement effect of mechanical properties. Up to now, most research paid attention on the improvement effect of different types of fiber or optimum fiber conten

catalysis by organometallic compound

1) what is alkene hydrogenation ? An alkene addition reaction is a process called hydrogenation . In a hydrogenation reaction two hydrogen atom are added across the double bond of an alkene resulting in a saturated alkene . The heat released is called heat of hydrogenation . 2) what is wilkinson's catalyst ? First effect homogenious catalyst is a square planner 16 electron d8 complex chlorotris (triphenyl phosphine ) rhodium(1) called wilkinson's catalyst . 3) what do you understand by Tolman catalytic loops ? A reaction involving a true catalyst can always be represented by a closed loop is called Tolman catalytic loops. 4)Explain the term hydroformylation ? Hydroformylation also called a oxoprocess or oxo synthesis It is an industrial process to prepare aldehyde from alkanes . In this process there is a net addition of formyl group(-CHO) and a hydrogen atom to a C = C double bond . This process is considered as very impo
