Mathematics: Post your doubts here!
(i) a = -d ; u = 1.4 ; t = 1.2 and v = 1.1 we first find the value of a, the deceleration v = u + at a = ( v - u ) / t = ( 1.1- 1.4 / 1.2 = -0.25 Hence d= 0.25 Distance ; s = (v^2 - u^2)/2 a = ( (1.1)^2 - (1.4)^2 ) / (2 * -0.25) = 1.5 m... -

y = ln(sinx/cosx-1) recall that ln (a/b) = ln a - ln b so we rewrite y = ln sinx - ln ( cosx - 1 ) recall d/dx [ln ( f(x)) ] = f ' (x) / f (x) hence dy/dx = cosx/sinx - ( - sin x / ( cosx -1 ) ) = cot x + sin x / ( cosx -1 ) -

send all x to dx and the others to dt such that dx / [ x ( a-x ) ] = k dt we then integrate both sides.But first We see that we will have to first do partial with 1/ [ x ( a-x ) ] 1 / [ x ( a-x ) ] = A /x + B/(a-x) 1 = A ( a-x ) + B x Let x = 0 ; Let x = a A = 1/a ... -

Are you sure of the question? y = 2 [( 1 - sinx ) ^ -1] Integrating will give us = -2 sec x ln ( 1 - sin x ) But i am not too sure of this answer that is the reason of my first question. May be someone else should confirm it... -

Lol, you tagged me. :) First Fact : I sat for this paper as a student for A Level and i so much enjoyed life as a college student. Miss these moments and my friends...Why did i grow up so soon...???lol. To Proceed; y = A x^n put log or ln on both sides ln y = ln ( A x^n ) ln y = ln A +... -

Because the domain of f(x) is less or equal to zero. Read the question well. -

Question 2. When you differentiated you got dy/dx = 9 x^2 - 12 x + 4 What you should next do is to complete the square. = 9 ( x^2 - 4/3 x ) + 4 = 9 [ ( x - 2/3 ) ^ 2 - 4/9 ] + 4 = 9 ( x - 2/3 ) ^ 2 - 4 + 4 = 9 ( x - 2/3 ) ^ 2 which will be positive for any value of x since when we square... -

Obviously the answer is going to be diferent. The point is not what is being converted, instead it is TO WHAT IT IS BEING CONVERTED. Let me explain to you. R^2 = a ^2 + b^2 i.e R = SquareRoot ( a ^2 + b^2 ) and α = tan inverse of ( b/a) Now if we are converting to R COS, then a is going...
