Fθ tan((13θ / 12) - cos((3θ)/ 4))の周期は?

24πの期間tan((13t)/ 12) - >(12pi)/ 13 cosの期間((3t)/ 4) - >(8pi)/ 3 f(t) - >の最小公倍数(12pi)/ 13と(8pi)/ 3(12pi)/ 13 ... x ..(26)...--> 24pi(8pi)/ 3 ... x ...(9)... .---> 24pi f(t) - > 24piの期間
Fθ tan((13θ / 12) - cos((6θ)/ 5))の周期は?

60π日焼け周期((13t)/ 12) (12π)/ 13 cos周期((6t)/ 5) (5(2π))/ 6 =(10π)/ 6 = (5π)/ 3の周期f(t) (12π)/ 13の最小公倍数と(5π)/ 3(12π)/ 13×(13)=12π×(5) - > 60pi(5pi)/ 3 .. x(3)....... = 5 pi x(12) - > 60 pi f(t)の周期= 60 pi
Fθ tan((13θ / 4) cos(θ/ 5))の周期は?

20πの期間tan((13t)4) - >(4pi)/ 13 cosの期間(t / 5) - > 10pi(4pi)/ 13と10pi(4pi)/ 13の最小公倍数を求める... x(5)(13)... - > 20pi 10pi ... x(2)... - > 20pi
