Use a graphing utility to graph the trigonometric function. Use the graph to make a conjecture about a simplification of the expression. cos(x) y = 1 - tan(x) sin(x) cos(x) sin(x) – cos(x) + The function appears to be y = Verify the resulting identity algebraically. (Simplify your answers completely.) cos(x)+ sin(x) cos(x) y = 1- tan(x) sin(x) – cos(x) cos(x) sin(x) cos(x) sin(x) – cos(x) 1 - cos(x) sin(x) cos(x) sin(x) - cos(x) cos(x) – sin(x) (cos(x)) cos(x) – sin(x)
