If `f(x)=sin[pi^2]x+sin[-pi^2]x`, where `[x]` denotes the greatest integer less than or equal to
A. `f(pi//2)=1`
B. `f(pi)=2`
C. `f(pi//4)=-1`
D. none of these

Text Solution

Verified by Experts

Given, `f(x)=sin[pi^2]x+sin[-pi^2]x`
`(pi)^2 = 9.8596`
So,
`[(pi)^2] = 9` and `[-(pi)^2] = -10`
So,
`f(x)=sin9x-sin10x`
