Also, (5) and (2) give 2m22 = (w + m3)2-2m1m3=m22-2m1m3, i.e. 7W22 + 2m1m3=0 (7).

Solving (6) and (7), we have 2a-ft, rt 2a-h 7713=--=--, and 7M2 =-2 x. Oa oa Substituting these values in (4), we have.2a--h h 2a-h I 2- oa a i.e. 21ak2 = 2(h-2a) so that the required locus is 21ay2=2(x-2af. If the normals at three points P, Q, and R meet in a point O and S be the focus, prove that SP. As in the previous question we know that the normals at the points (am12, -2am1), (am22, -2am2) and (am32, -2am3) meet in the point (ft, k) if m1 + m2 + m3 = 0 (1), 2a-ft m2m3 + m+711-2 =-----(2), k and m1m2m3=--(3).

Find the locus of a point 0 when the three normals drawn from it are such that 1. Two of them make complementary angles with the axis. Two of them make angles with the axis the product of whose tangents is 2. One bisects the angle between the other two. Two of them make equal angles with the given line y=mx + c. The sum of the three angles made by them with the axis is constant. The area of the triangle formed by their feet is constant.

The line joining the feet of two of them is always in a given direction. The normals at three points Pf Q, and 12 of the parabola y2--4ax meet in a point 0 who.

Author by: Isaac Todhunter Language: en Publisher by: Ancient Science Publishers Format Available: PDF, ePub, Mobi Total Read: 56 Total Download: 162 File Size: 45,5 Mb Description: Highly Recommended for IIT JEE and Olympiads 1000+ Problems with Solutions and 100+ Articles This book collects together the problems set out at end of each chapter in the author's Textbook of Plane Trigonometry along with the possible solutions, which are linked with an explanation of the sort of reasoning used in order to arrive at one of the answers. In many cases, several answers are given for one question. The result is a book which can be used independently of the main volume.

This book helps in acquiring a better understanding of the basic principles of Plane Trigonometry and in revising a large amount of the subject matter quickly. It is also to be noticed, that each Example, or Problem is here enunciated at the head of its Solution as well as all the relevant articles are part of the appendix; so that the book, though a fitting Companion to the textbook, is not inseparable from it, but may be used, as a Book of Exercises, with any other treatise on Plane Trigonometry. We are grateful for this opportunity to put the materials into a consistent format, and to correct errors in the original publication that have come to our attention. We are highly indebted to Chandra Shekhar Kumar for the fruitful discussions which led to the idea of masterminding this entire project. He helped us put hundreds of pages of typographically difficult material into a consistent digital format. The process of compiling this book has given us an incentive to improve the layout, to double-check almost all of the mathematical rendering, to correct all known errors, to improve the original illustrations by redrawing them with Till Tantau's marvelous TikZ.
