Verify that (sinA)^2 + (cosA)^2 = 1 for this angle measure
What is no
400
A method used to check whether or not a relation is a function. Imagine a vertical line moving horizontally along the x-axis. If this vertical line intersects the graph in at most one point at any x-coordinate, then the relation is a function. Otherwise, the relation is not a function.
