I don't know what "same context" means in regard to equations. The two equations areDoes y = x and y=(x+1)(sin^2x+cos^2x) -1 have the same context?

y = x may have context not similar to y = ( x + 1)( sin^2x + cos^2x ) - 1...

**equivalent**, meaning that they both represent exactly the same points, and their graphs are exactly the same.

No, they are both linear equations, meaning that the graph of each equation is a straight line. Both graphs pass through the origin, and both graphs have a slope of 1.First one is linear equation (straight lines) and the second equation is trigonometric equation (side lengths and angles).

Already answered -- both are straight lines through the origin with a slope of 1.What could y = x be?

What could y=(x+1)(sin^2x+cos^2x) -1 be?
