With Reference for understanding the purpose, I prefer S.Chand for science & for 10th board question practice I advise you to continue with NCERT books. For Maths R.D. Sharma is the best alternative as it contains lots of variety of question with answers & having an additional knowledge as well so I advise you to go understand the concern the syllabus from NCERT book before start doing practice from R.D. Sharma. For Social Science, Hindi, English, NCERT books are more than sufficient. For English you may also consult "Golden English Communicative" it contains both Class 10 syllabus in details with Sample Papers. Last but not the least NCERT is must so please don't ignore it, About 70% - 80% question come from NCERT only so please go through it. For the Understanding purpose I advise you to first read NCERT & then after that the referral books which I mentioned above.

Indeterminate form means you cannot be certain about the value of that given problem or number.
For example..
F(x)= g(x)h(x) were g(x)=4 and h(x)=5, then you can easily say f(x) is 20.
But if g(x)=0 and h(x)=infinity,
You cannot say what f(x) will be.
This is the indeterminate form.
Such forms can be evaluated with the help of L Hospital rule.

Dear Kudo,
Coordinate Geometry is nothing but naming a point based on his position from the axis. This branch of mathematics finds a large application in computer graphics. There is no other effective way in Computer Science (not that I can think of) to generate mathematical figures. It is used in astrophysics (say calculation of distance between two celestial bodies), geography, architecture (how would you accurately represent relative distance between and sizes of multiple objects unless you have a frame of reference).
One of the Most basic and common example of Coordinate Geometry which we use in our daily routine life is "Google Maps".
When we instruct google maps to tell us the path from one place to another, it basically:
1.Finds the shortest possible path (or paths).
2.Tells us the distance and time.
3.There are Lots and lots of coordinate geometry is used in finding the shortest path and the distance between them. Obviously, there are other concepts (OR) principles involved too.
4.Once we have the distance, an approximate time to travel is calculated based on the traffic.

Mode:
A statistical term that refers to the most frequently occurring number found in a set of numbers. The mode is found by collecting and organising the data in order to count the frequency of each result. The result with the highest occurrences is the mode of the set.

Eg: 3, 3, 6, 9, 16, 16, 16, 27, 27, 37, 48 -------------------Mode is 16

therefore GM=square root of (2 x 18)
GM=sqrt (36).

Class limits are the smallest and largest observations (data, events etc) in each class. Therefore, each class has two limits: a lower and upper.
Class interval is the difference between the upper and lower class boundaries of any class.

Not possible because, sum of all 3 angles together, should be 180 degrees.
Here, sum of the the given 2 angles is > 180 degrees.

Parshva replied | 01 Jan

To form a triangle the sum of interior angles of a triangle is equal to 180 but as the scenario here is the sum of only given two triangles is 185 degree then definitely it is not possible to build a triangle with given angles.

In simple words, discrete frequency occurs at discrete interval(e.g. at 1 sec, 2 sec, 3 sec etc.). But continuous frequency occurs at every point in continuous manner without leaving gaps (e.g. every moment b/w 1 to 2 secs).

Prabhneet replied | 11/12/2016

The harmonic mean is a better "average" when the numbers are defined in relation to some unit. The common example is averaging speed. The GM is for situations we want the average used in a multiplicative situation, such as the "average" dimension of a box that would have the same volume as length x width x height. For example, suppose a box has dimensions 50 x 80 x 100 cm.

An arithmetic sequence is a sequence of numbers with the difference between two consecutive terms constant. The difference is called the common difference. A geometric sequence is a sequence with the ratio between two consecutive terms constant. This ratio is called the common ratio.
