535for the first one, i was also getting (a)
and 2nd one too, my answer was coming to be 0.

1133For the first one,
cosx = f(sinx)
=> (1-x2)1/2 = f(x)
=> 0 ≤ f(x) ≤ 1
- Aditya Agarwal wont we be considering "t" to be the variable?
- Sourish Ghosh yea, let t = x + h. what's the answer btw?
- Aditya Agarwal i dont know, yet.
a friend gave it to me to solve, it came in a test he gave.
- Sourish Ghosh Is the 2nd answer 0?
- Aditya Agarwal i got the answer as 0 only..
