draw the graph of 4sin(x+30) and 2+tanx for values of x from 0 degree to 360degree and obtain the solution within the range of the equation 4sin(x+30)-tan x=2

    I can't draw it for you.

    We can't draw graphs for you, but you will get the solution(s) to your equation where the two curves intersect.

    That is because, when
    4sin(x+30) = 2+tanx ,

    4sin(x+30) -tan x = 2

    Assume the 30 is in degrees.

    Sample calculations:
    when x = 0, 4sin(x+30) = 2.000
    and 2 + tanx = 2
    That is one solution already!
