form a quadratic in cosA
which gives
(a+b)cos^4A-2bcos^2A+b^2/a+b =0
By Shreedharacharya's rule--
cos^2A=2b/2(a+b)= b/a+b .... (1)
sin^2A=a/A+b ..... (2)
thus we have---
In the required expression these values give (1/a+b)^3
Hence Proved

The method above is lengthy but I have a short cut technique
GIVEN IN BOOK BY T.W. Solomons.(8th edition)

I think 1-Methyl propanol is a wrong IUPAC name.

CH2--CH2--CH3

OH WILL BE NAMED AS 2-BUTANOL

No of ways is = 28 x 28 x 28 Ans.

Total no of lines drawn= m x n= mn
for intersection two lines are required thus-
no of points of intersection = mn c 2 Ans
Q.)---Am I correct?

Please name the compound---

HOOC--CH2-CH2--O--CH2--CH2--O--CH2--CH2--COOH ?

{ GIVE THE RULE BEHIND IT ALSO........ PLEASE}

Since the rod is in translational motion the sum of the two antiparallel forces should be zero else the rod will execute circular motion.This means that the other force must also be at a distance
L from the centre..
Hence the length of rhe rod should be 2L.

GOOD QUESTION .

I HAVE CONTACTED THE INTERNATIONAL COMMUNITY OF PHYSICS AND THEY ARE TRYING TO FIND THE LADDER AND THE BLOCK.
BE PATIENT THEY WILL FIND THE LADDER AND THE BLOCK AND GIVE YOU THE ANSWER MY FRIEND.

1,3,5,7,9----------->
Total numbers=5x4x3x2x1=120
All numbers are of 5 digits hence
120/5=24
Each digit will occur at a position 24 times in the whole addition list
Units place=(1x24)+72+120+168+216=600---0 and carry 60
Tens place=600 +60=660----0 and carry 66
hundreds place=600+66=666-----6 and carry 66
thousands place---6 and carry 66
tenthosands place--666
THEREFORE WE GET----6666600 ANSWER

THIS IS NOT A PROOVED THEORY AND I WOULD SUGGEST YOU TO GIVE EQUAL TIME FOR THESE CHAPTERS BECAUSE AT LEAST FLUID MECHANICS CAN BE SOMETIMES ENGAGED WITH NEWTONS LAWS.

Pseudo force is nothing but a force that seems to be acting on a body due to its motion on account of another body and it is just enough to know that pseudo force will always act opposite to the actual force on the body on whose account this body is actinng.

FOR INSTANCE-->a inclined plane has a block on it and the incline along with the block moves towards the left then a pseudo force acts on the block in the opposite i.e. towards the right.
