the graph of cos(x)=1 when x=0 the graph of sin(x)=0 when x=0. But that only tells part of the story. The two graphs are out of sync by pi/2 radians (or 90°; also referred to as 1/4 wavelength or...
An exponential function is of the form y = a^x, where a is a constant. The inverse of this is x = a^y --> y = ln(x)/ln(a), where ln() means the natural log.
In general the function and it inverse are not the same and do not have the same graph.
If we look at a special function f(x)=x, it is equal to its inverse and the graph is the same.
Think of the...
The function y = x is the graph that passes from the points (-1, -1), (0, 0), and (1, 1) The function y = 4x is the graph that passes form the points (-1, -4), (0, 0), and (1, 4) Sketch these graphs...
