how to graph sin and cos graphs HELP PLEASE!!!
|dw:1331091734495:dw||dw:1331091866317:dw|
the quadrents for sin and cos are |dw:1331091944892:dw|
okay thank you and how would u find and equation if the graph is already given?
equations are sin(x) and cos (x) respectively. They are the fundemental characteristic graphs of sin and cos
how would you find the equation of this graph?
so the equation for this would be y=sin(x). as you can see in the quadrent thing i have posted above, sin(0)=0, sin PI/2=1 , sin PI= 0, sin 3Pi/2=-1, sin 2Pi=0 so according to this they have drawn the graph.
