(sin(8*x)*sin(7*x))'The calculation above is a derivative of the function f (x)
(sin(8*x))'*sin(7*x)+sin(8*x)*(sin(7*x))'
cos(8*x)*(8*x)'*sin(7*x)+sin(8*x)*(sin(7*x))'
cos(8*x)*((8)'*x+8*(x)')*sin(7*x)+sin(8*x)*(sin(7*x))'
cos(8*x)*(0*x+8*(x)')*sin(7*x)+sin(8*x)*(sin(7*x))'
cos(8*x)*(0*x+8*1)*sin(7*x)+sin(8*x)*(sin(7*x))'
8*cos(8*x)*sin(7*x)+sin(8*x)*(sin(7*x))'
8*cos(8*x)*sin(7*x)+sin(8*x)*cos(7*x)*(7*x)'
8*cos(8*x)*sin(7*x)+sin(8*x)*cos(7*x)*((7)'*x+7*(x)')
8*cos(8*x)*sin(7*x)+sin(8*x)*cos(7*x)*(0*x+7*(x)')
8*cos(8*x)*sin(7*x)+sin(8*x)*cos(7*x)*(0*x+7*1)
8*cos(8*x)*sin(7*x)+sin(8*x)*7*cos(7*x)
8*cos(8*x)*sin(7*x)+7*sin(8*x)*cos(7*x)
