Where in the figure are there nodes at t1?
Please post your working.

Hi haruspex, thank you for yr time to have a look at my question. the Figure doesn’t include nodes/anti nodes.

That's only because the figure doesn't plot g+h. You can easily see where the nodes must be.

You seem to have completely misunderstood the question.
You have to find a place where g+h is always zero.
