Practise make perfect ! For me , the way to get good result in calculus is practise more . Maths do not requires memorizing but undertanding and practise. Cheer..

hehehe..in my opinion , as the process on solving the mathematic problem may take long solution and applying many formula . To avoid confusing and easy to solve , so the mathematicians introduce those symbol to make the job easy. e.g : pai = 3.142... a x b = a.b = ab ( multiplied ) . a...

Thanks a lot...

let me try sin (4x) = 4 sin x cos *3 x - 4 sin *3 ( x ) cos ( x) let 2x = X sin 2X = 2 sin X cos X =2 sin 2x cos 2x =2 [( 2sinx cosx ) ( cos*2 x - sin *2 x ) ] =2 [ 2sinxcos*3 x - 2sin*3cos x ] = 4sinx cos*3 x - 4sin*3 x cos x

Question : Need your help. Can anyone please help me to solve this problem..please.. ln(ln(ln(ln x+4 ))) = e
