Let's remind ourselves of what the sine graph looks like so that we can see how many solutions we should be expecting: Therefore, from the graph of the function ... the trig equation we are ...

You can perform multiple actions, such as zooming in and moving the graph to observe intersection points or changing the values of parameters in your equations ... 3 or y=sin(x)+cos(2x).

Initially launched as a way to give you tips on solving difficult math equations lat year, OneNote's Ink math assistant can now draw graphs of your ... y=x+3 or y=sin(x)+cos(2x).
