If `f:R->R, f(x)=sin^2 x + cos^2 x`, then f is

If f : R rarr R , f(x) = sin^(2) x + cos^(2) x , then f is

If f : R rarr R , f(x) = sin^(2) x + cos^(2) x , then f is

Classify f: R->R , defined by f(x)=sin^2x+cos^2x as injection, surjection or bijection.

For a real number x, lel [x] denotes the griater + integer less than or equal to x. let f:R rarr R be defined by f(x)=2x+[x]+sin x cos x then f is:

Let f:R rarr R, be defined as f(x)=e^(x^(2))+cos x, then f is a

Let, f: R rarr R be defined by f(x) = 2x + cos x, then f

If f: R rarr R , f(f(x)) = (f(x))^(2) , then f(f(f(x) ))is equal to

If f(x)=(cos^2x+sin^4x)/(sin^2 x+cos^4x), for x in R, then f(2002) is equal to

f : R to R : f (x) = cos x is
