cos(left(2n+1right)90) eching

$$\cos ( \left( 2n+1 \right) 90 )$$

n ga nisbatan hosilani topish

$$-180\sin(90\left(2n+1\right))$$

Zanjirli qoidadan foydalanish qadamalari

2n+1 ga 90 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$\frac{\mathrm{d}}{\mathrm{d}n}(\cos(180n+90))$$

Agar F ikki differensial funksiya f\left(u\right) va u=g\left(x\right)'ning yig'indisi bo'lsa, ya'ni agar F\left(x\right)=f\left(g\left(x\right)\right) bo'lsa, F hosilasi f'ning u martalik hosilasi, g'ning x martalik hosilasi ya'ni \frac{\mathrm{d}}{\mathrm{d}x}(F)\left(x\right)=\frac{\mathrm{d}}{\mathrm{d}x}(f)\left(g\left(x\right)\right)\frac{\mathrm{d}}{\mathrm{d}x}(g)\left(x\right) bo'ladi.

$$\left(-\sin(180n^{1}+90)\right)\frac{\mathrm{d}}{\mathrm{d}n}(180n^{1}+90)$$

Polinomialning hosilasi bu uning shartlari hosilasining yig‘indisiga teng. Konstant shartning hosilasi 0. ax^{n} ning hosilasi nax^{n-1}.

$$\left(-\sin(180n^{1}+90)\right)\times 180n^{1-1}$$

Qisqartirish.

$$-180\sin(180n^{1}+90)$$

Har qanday t sharti uchun t^{1}=t.

$$-180\sin(180n+90)$$
