Sin(3π/2)= 1/2

=> f(1/2) = (1/2)²-3(1/2)+5
             =15/4
And,

Cos(3π/2)=-1/2
=>f(-1/2)=27/4

summing up both as required,
=> (15+27)/4
= 42/4

sin(3pi/2)=-1 so the entire sum is wrong na
correct answer is 8 isn't it?

Sin 3 pi/2=-1 Thus,f(1)= 1+3+5=9 Cos 3 pi/2=-1/2 Thus,f(1/2)=1/4+3/2+5=27/4.. Hope it helps :)

its wrong
sin 3pi/2=-1 then f(-1)=9,cos3pi/2=0 then f(0)=5 then answer is 9+5=14
