For 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..
