Plz help me i really dont get this... Use a graphing calculator to approximate the solutions of theequation in the interval [0,2) My teacher told me to first graph it, then press second chartor something, then find x intercept... i dont get it 2sinx+cosx=0 i just need to noe the steps and then i will rate uimmediately Plz help me i really dont get this...

Explanation / Answer

Plug in y= 2sinx + cosx
change the window to xmin = 0 and xmax = 2 (make sureyou're in radian mode) Identify all points on the horizontal axis (x-axis) where theline crosses... These are the x values that satisfy the equation... (If you can't find the values by just looking at the graph,add y= 0 and find the intercepts because y= 0 is just thex-axis) If you have any additional questions just PM me... Hope thishelps!
