physics textbook, replace sine with its definition (?)
What on Earth do they mean?
"That will introduce either sin(theta) or cos(theta). Reduce the resulting two variables, x and theta, to one, x, by replacing the trigonometric function with an expression (its definition) involving x and y."
Replace sin(theta) with a function of x and y? What?
