Which of the following numbers are co-prime: 18 and 35.

In each of the following cases, write the rational number whose numerator and denominator are respectively as under: 35 div (-7) and 35 - 18

Evaluate: (cos 58^@)/(sin 32^@)+(sin 22^@)/(cos 68^@)-(cos 38^@cosec 52^@)/(tan 18^@tan 35 ^@ tan 60^@tan 72^@tan 55^@) .

If Tan A = (17)/(18), TanB = (1)/(35) then Cos (A+B) =

If tanA=18/17 and tanB=1/35 prove that tan(A-B)=1
