Question Number 160310 by HongKing last updated on 27/Nov/21
find the period of the function:  y = tan ((πx)/k) + cos ((2πx)/(k + 5))
$$\mathrm{find}\:\mathrm{the}\:\mathrm{period}\:\mathrm{of}\:\mathrm{the}\:\mathrm{function}: \\ $$$$\mathrm{y}\:=\:\mathrm{tan}\:\frac{\pi\mathrm{x}}{\mathrm{k}}\:+\:\mathrm{cos}\:\frac{\mathrm{2}\pi\mathrm{x}}{\mathrm{k}\:+\:\mathrm{5}} \\ $$

period=lcm(k, k+5)
$${period}={lcm}\left({k},\:{k}+\mathrm{5}\right) \\ $$
