sin is a function, which means you must give it an input. The error here is with the code sin*t at the end of your expression. Did you mean sin(t)? Take a look at the documentation page for sin for more.

You have it partially correct.

Try this:

y4 = sin(t) .* sin(t);

If you want to multiply thge second one by ‘t’ do this:

y4 = sin(t) .* sin(t).*t;

This uses element-wise multiplication (the dot operator, so .* instead of *). I n the event that ‘t’ is a vector, it will produce a vector result. It will also work correctly if ‘t’ is a scalar.
