To find the equation perpendicular to the given line, we need to factorise it.  

Consider x2 - 5xy + 4y2 = 0.

Or, x2 - 4xy – xy – 4y2 = 0

Or, x(x  - 4y) – y(x - 4y) = .....

Arthematic series is the series of number having common difference. For simplicity you can assume the 3 numbers in Arthematic series as: a - d, a and a + d. Now, by the question, The sum of three terms = 21 That is, (a - d) + a + (a + d) = .....

From the question you have to understand that, the fall is in geometric series  with common ratio ; r = 1/2. Here distance covered in frist fall = a = 64 m  For 7th fall,  n = 7 So distance covered in 7th fall is t7 = a rn - .....

To prove this, we have to use the following formula. Formulas used:  1. (a+b)^3 = a^3 + b^3 + 3ab (a+b)  2. sin 2x = 2 sin(x) cos (x)  3. cos^2 (x) = (1+cos (2x)) / 2  It implies that, cos^2 (2x) = (1+cos (4x)) / 2  4. .....

Here  take LHS because it is long and complicated. So lets take LHS. Use formula  CosC - CosD = 2Sin[(C+D)/2]Sin[(D-C)/2] in numerator by supposing C = a  and  D = 5a. Use formula 

SinC - SinD = .....

To factorise it, we have to use a idea, otherwise we van not do. i.e ; x3 - 1 / x  =x3 - x.1 / x 2 Taking x common we get, = x( x2 - 1/ x2) = x( x2 - 1/ x2) =x { x2 - (1/ x)2 }   Now put in formula .....
