Computation method
Whereas L = Lower class boundary of the class having the mode
f0 = Frequency of the class below the modal class
f1 = Frequency of the class having the mode
f2 = frequency of the class above the modal class
c = Class interval
Hence mode = 60.50 +[(48 - 32)/{{2(48)} - 32 -27}] * 20
= 69.14
Prove that sec 2 θ+cosec 2 θ can never be less than 2. Ans: S.T Sec 2 θ + Cosec 2 θ can never be less than 2. If possible let it be less than 2. 1 + Tan 2 θ + 1 + Cot
L.H.S. =cos 12+cos 60+cos 84 =cos 12+(cos 84+cos 60) =cos 12+2.cos 72 . cos 12 =(1+2sin 18)cos 12 =(1+2.(√5 -1)/4)cos 12 =(1+.(√5 -1)/2)cos 12 =(√5 +1)/2.cos 12 R.H.S =c
