a) Prove cot 2 q + 1 = cosec 2 q . We know that cos 2 q + sin 2 q = 1 ...(1) also Divide (1) by sin 2 q on both sides (sin q 0), then b) Prove that 1 + tan 2 q = sec 2 q . ..

From the above observation, we find (i) sin A = cos B where A + B = 90 o \ Sine of an angle = Cosine of its complement sin A = cos (90 - A) o sin 40 o = cos (90 - 40) o = cos 50 o (ii) = tan A (iii) By Pythagoras theorem a 2 + b 2 = c 2..

Given a, b, c and d are non-zero real numbers, we can deduce other proportions by simple Algebra. These results are often referred by the names mentioned along each of the properties obtained. (1) If then bc = ad This property is known as INVERTENDO. (2) If , then ad = bc This property is..
