Question

f(t)=sin t is an odd function g(t)=cos t even function
what can be said about h(t)=f(t)g(t) ??????

Answer 1

h(-t) = f(-t) g(-t) = -f(t) g(t) = -h(t)

so h(t) is odd

Answer 2

omg ily THANKS

Answer 3

this is true no matter what f and g are.

notice that sin(t) cos(t) = (1/2) sin(2t), which is odd
