A person standing on the bank of a river, observes that the angle subtended by a tree on the bank is 60 o . When he retreats 20m from the bank, he finds the angle to be 30 o . Find the height of the tree and the breadth of the rive..

Find the general solution of the following equations: 4) cos q - cos q =..

is that branch of mathematics which deals with the measurement of sides and angles of triangles. The word, trigonometry is derived from Greek, which means the measure of triangles. This subject was originally developed to solve problems in astronomy and geometry. In recent times, the su..

Trigonometry - With trigonometry we can find the height of a building or the width of a river without actually climbing or crossing. Certain basic definitions are necessary to further develop this subject. The ratios of two sides of a triangle are taken. There are six possible c..

(i) Sin q means a particular ratio. It is not sin multiplied by q . (ii) For trigonometrical ratios, short form T-ratios will be used. (iii) In right angled triangles T-ratios are obtained only for acute angles. (iv) T-ratios depend on only the magnitude of the angles and..
