Mathematics: Post your doubts here!
I just know one thing here : f (x) = sin (x) / x dy/dx = [ d/dx (sin (x) ) * x - (sin (x) ) * d/dx (x) ] / x² dy/dx = [ cos (x) * x - (sin (x) ) ] / x² dy/dx = [ xcos (x) - sin (x) ] / x² dy/dx = ( x cos (x) / x² ) - ( sin (x) / x² ) dy/dx = ( cos (x) / x ) - ( sin (x) / x² )- Thought blocker

abcde credits. (Part ii) i) T = F and F = μR T = μR From the figure you can see T = 2N and R = 3N and μ = T/R = 2/3 ii) As the system is in limiting equilibrium, the tension would equal A's weight i.e. 2N. As A is about to move upwards, B is about to move rightwards. So the frictional force now...- Thought blocker
