In my opinion, most of the students would have done great in maths in childhood (say 1st to 4th STD), not because they were studying well, it might be because the concepts were easy. But what happens...
If sinα =3/2, find the value of all T- ratios of α If cosα =7/25, find the value of all T-ratios of α If tanα =15/8, find the values of all T-ratios of α If cotα...
an = a+(n-1)d Where an=last term a=first term d=common difference n=number of term Note: last term is denoted by an or l Sn=n/2[2a+(n-1)d Sn=sum of all terms
