15. What is the derivative of the function: *
F(x) = x cos(5x)
F(x) = x cos(5x)
F'(x) = (x) cos(5x)+(cos(5x)) (x)
F'(x) = cos(5x) + [-sin(5x) (5)] (x)
F'(x) = cos(5x) - 5x sin(5x)
Option.
F(x) = x cos(5x)
F'(x)=(x) cos(5x)+(cos(5x)) (x)
F'(x) = cos(5x) + [sin(5x) (5)] (x)
F'(x) = 5x sin(5x) - cos(5x)
Option;
F(x) = x cos(5x)
F'(x) = (x) cos(5x) + (cos(5x)) (x)
F'(x) = cos(5x) + [sin(5x) (5)] (x)
F'(x) = cos(5x) + 5x sin(5x)
Option,
