Using a graph format in excel, plot the following function; Y=2SinӨ + 3CosӨ for values of Ө between 0 and 90???. From the graph find; a.the maximum amplitude of the function. 2.A value of Ө which satisfies the equation 2SinӨ + 3CosӨ = 3.5 As evidence, you are required to show what formula you have used to produce the graph. - ok well.. i put 2 in sin, and 3 in cos and did them added together to give a value, and tryed to make a graph.. i dont get the question, or what im ment to do, or anything. please could someone help explain or give asmuch help as possible.
