q1 Find intervals of continuity,differentiability
1) sin-1(1+x22x)
2) [x[1-x]]
[.] denotes Greatest Integer function
q2 Find Domain and range
1[sinx]
q3 f(x) and g(x) are twice differentaible functions in [0,2].
If f"(x)=g"(x),f'(1)=2,g'(1)=4,f(2)=3,g(3)=9.Find value of f(x)-g(x) at x=4
q4 f:R→R .If \left| f(x)\right| \leq x^2 ,x ε R.Find f'(0)

1For the second question ..
domain is x[(2n+1)Î ,2(n+1)Î ] U {(2n+1)Î 2}
and range is {-1,1}
