Sir I can't solve problems related to these chapters what should I do .please help me I am in trouble
Generally its easy for me to understand chapters but i am extremely unable to understand haloalkanes and haloarenes what to do now? I have watched videos many times but its not helping this time.
How should I solve the proving questions in trigonometry? Pls help.
Like for example:-
sinA(1+tanA) + cosA( 1+cotA) = secA + cosecA.
I am facing problems in these kinds of questions. How should I proceed when I get these questions. (I can solve this particular question but don’t know how to tackle other questions of the same kind)
I had a doubt that while practising a chapter in maths, after completing all the NCERT problems in that chapter , should I first complete seeing the board questions of previous year of that particular chapter OR should I first complete all the NCERT sums of all subjects and then on the whole refer to questions on other resources. Please give me a proper method of learning for class CBSE 12 to score above 90 . Help me with your guidance
