What do you do if a particular integral you want to evaluate is not listed in the table?
Two main options.
- Carry out numerical integration - there are various methods - the trapezium method being one of the simpler ones; or
- find two integrable functions such that one is greater than the given function and the other is smaller than it. Then your integral will lie between the integrals of these two functions.
How is trigonometry used in land surveying?
Trigonometry is basically formula's to help you find out unknown sides and angles of a triangle.
Surveying is measuring land. But as not all land is equal so these formula's are used to help.
Application of relation between arc of length and central angle?
The relation between the arc of length and the central angle is that the arc of length divided by one of the sides is the central angle in radians. If the arc is a full circle, then the central angle is 2pi radians or 360 degrees.
Where did the word golf come from?
The word is first known in English from the 15th century from Scots. Although the etymology is uncertain, the most likely origin is thought to be from the Middle Dutch colf ("'club'").
How do you write y equals 4cos1over2x as a horizontal shift of the other function?
You cannot since the transformation is not a horizontal shift.
What is a vertical line look like?
It is a straight line that goes up. In 2-dimensional geometry it usually goes up the the page whereas in 3-d it is the line that goes upwards - towards the sky!
What is the volume of the triangular prism if there are four numbers on the shape?
Assuming that the prism is a right triangular prism and that the 3 of the numbers are the lengths of the sides of the triangle, and the 4th is the length of the prism,
Suppose the sides of the triangle are a, b and c units and let s = (a+b+c)/2
then area of the triangle = sqrt[s*(s-a)*(s-b)*(s-c)]
and so, if the length of the prism is d,
its volume = d*sqrt[s*(s-a)*(s-b)*(s-c)]
How do I do the following equation step by step Tan(30)x7.5 ROOT 2?
Correction: the problem is Tan(30)= x/ 7.5 root 2
Where did the word 'Medieval' come from?
It comes from the Latin phrase "medium aevum," meaning literally "the Middle Age."
It would have been much simpler if this browser had halfway decent graphic facilities but it does not so you may have do a few sketches as you go along..
The bowl is tipped by 35 deg so the diameter of the bowl makes a 35 deg angle with the horizontal. The surface of the water must be horizontal and so that makes an angle of 35 deg with the tipped diameter.
Therefore [in cross section] the water occupies a segment of a circle such that the angles between the water surface and the radii at both ends on the segment are 35 deg. Therefore the segment subtends an angle of 110 deg at the centre. Also, the radii are 20 cm.
In the triangle formed by the water surface and the sides of the segment, the distance from the centre of the bowl to the water surface is 20*sin(35) = 11.47 cm. Therefore, the depth of the water is 20 - 11.47 = 8.53 cm.
