tan225=tan(125+100),


tan(180+45)= (tan125+tan100)/(1-tan125tan100),


tan45=(tan125+tan100)/(1-tan125tan100),


1=(tan125+tan100)/(1-tan125tan100),


tan125+tan100=1-tan125tan100,


tan125+tan100+tan125tan100=1.

Thanks, Arun. If you google "2 tan b + cot b" the very first link is JEE Main Mathematics by Prem Kumar, and clicking that link will bring you to the problem. The other book is Mathematics...

Dear Achal, Then I am sorry, because as far as I know it would not be possible to solve the question. But, if you can say which textbook you are referring to, then maybe I may be of help.

How many pairs of natural numbers are there, the difference of whose squares is 45? a) 3 c) 4 b) 5 d) 6
 
 
a ​2 - b ​2 =(a-b) (a+b) = 45 = 1*45 = 3*15 = 9*5 just solve these cases and seefrom which natural number are coming. for eg a-b=5 a+b=9 from this a=7and b=2

shortest distance between the skew lines r=(i+2j+3k)+t(i+3j+2k) and r=(4i+5j+6k)+(2i+3j+k) is?
 
 
for shortest distance between skew lines we use a formula d=(a2-a1).(b1*b2)/mod(b1*b2) where a1 and a2 are points from which the given two lines are passing b1 and b2 are direction ratios...
