draw them both out on a graph and then draw the line y=x through the origin. If one function is a reflection of the other, it is the inverse
a data i like a graph it could be any kind of graph pie,bar,line graph
secx is the inverse of cosx. secx=1/cosx. A secant is also a line drawn through the graph that touches two points on a function.
symmetric about the y-axis symmetric about the x-axis symmetric about the line y=x symmetric about the line y+x=0
