  • "At Math 151: Male, Black hair. My love for you is like a concave up function because it is always increasing."
  • "Gooseberry says Hate to break it to you but a concave up function can have a negative first derivative and therefore be decreasing. Look at f(x) = sin(x) f'(x) = cos(x) f''(x) = -sin(x) At 7π/6 it is concave up f''(7π/6) = -sin(7π/6) = -(-1/2) = 1/2 however f'(7π/6) = cos(7π/6) = -sqrt(3)/2 which is negative which implies that the function is decreasing, even though it is concave up."
