Find the range of f(x)=cos[x],for x lies between -pi/2 to pi/2Thanks for giving answer to my query but Iwould like to inform that I am not able to understand the solution pls explain it in detailsolution given by you earlierThe given function is f(x)=cos[x],for -pi/2Since the angle is [x] so the interval -pi/2 1. -pi/2 2. -1 3. 0 4. 1 In the interval -pi/2 So, cos [x] = cos(-2) = cos 2In the interval -1 So, cos [x] = cos(-1) = cos 1In the interval 0 So, cos [x] = cos0 = 1In the interval 1 So, cos [x] = cos1Thus, the range of f(x) = cos[x], for -pi/2
