y=cos x for 0<=x<=pi what is the graph?

Answer 1

A wave with y-values going from 1 to -1. An x-intercept exists at pi/2

Answer 2

for a graph, go to www.quickmath.com, click on Solve under Inequalities, then click advanced, then type in

y = cos(x)
0 <= x <= pi

This will give you a graph.

Answer 3

basically they are telling you that your domain (the x values) are between zero and 3.14 (pi). for example you would plug in cos0. all the way to cos3.14
