PROBLEM: Eliminate the arbitrary constants (:1 and (:2 using direct differentiation method then write the differential equation of the function y=c1 oos(x"2+c2). In writing your nal answer, follow the format 2xyy"3yy'+x'\"3y2xy'2=0. Strictly no spaces between symbols and the order of the derivative is from highest to lowest. If it involved it and y, write x first followed by y whatever the exponent be. Do not use grouping symbols for the product or multiplication symbol. Use the symbol f\") caret to denote the exponent of the variable
