Trigonometry Introduction
Introduction - In Greek 'Trigonon' means a triangle. 'Metron' means a measure. The combination of these two words gives us the word 'Trigonometry'. Trigonometry is the branch of mathematics that deals with the relations between the sides and angles of triangles. In our..
Trigonometry (Continued) Introduction
Introduction - An equation containing the trigonometrical functions of an unknown quantity is termed as a trigonometrical equation , which holds for some values (and not for all values) of the quantities involved. The value, that satisfies the equation are called the roots . The main prob..

Introduction
The height of a building or the width of a river can be measured without climbing or crossing it. In this chapter we will show how it is made possible. Some suitable angles and distances will be measured to achieve the above result..
Introduction
When calculating sides or angles of right angled triangles, it is easiest to use the appropriate trigonometric relation. Finding the value of trigonometric ratios from the tables is learnt easily. Nowadays of course calculators are able to give accurate values for any degree of tan, sin..
Introduction
The t-ratios of acute angles are given in tables of natural sines, natural cosines and natural tangents. In this chapter, we will discuss (i) how to read trigonometric tables, (ii) how to find the angle when the value of a t-ratio is give..
Introduction
Let us recapitulate the trigonometric ratios (t-ratios). There are six t-ratios. D ABC is a right-angled triangle, B = 90 o . (i) In short, (ii) In short, (iii) tangent A tangent A In short, tan A Similarly three more ratios can be obtained by taking the reciprocals of sine, cosine and tangent rati..

I need tutoring from tutorvista till th end of my schooling. Tutors are not only experts they are brilliant enough to make a student like me understand the concepts of differentiation and functions.
The tutor remembered me from last week and noted my improvement. This is simply amazing :)
