Whakaoti i te 1/2|13|(6/k)

$$\frac { 1 } { 2 } | 13 | ( \frac { 6 } { k } )$$

Aromātai

$$\frac{39}{k}$$

Ngā Upane Otinga

Ko te uara pū o tētahi tau tūturu a ko a ina a\geq 0, ko -a rānei ina a<0. Ko te uara pū o 13 ko 13.

$$\frac{1}{2}\times 13\times \frac{6}{k}$$

Whakareatia te \frac{1}{2} ki te 13, ka \frac{13}{2}.

$$\frac{13}{2}\times \frac{6}{k}$$

Me whakarea te \frac{13}{2} ki te \frac{6}{k} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{13\times 6}{2k}$$

Me whakakore tahi te 2 i te taurunga me te tauraro.

$$\frac{3\times 13}{k}$$

Whakareatia te 3 ki te 13, ka 39.

$$\frac{39}{k}$$

Kimi Pārōnaki e ai ki k

$$-\frac{39}{k^{2}}$$

Ngā Upane e Whakamahi ana i te Tautuhinga o te Pārōnaki

Ko te uara pū o tētahi tau tūturu a ko a ina a\geq 0, ko -a rānei ina a<0. Ko te uara pū o 13 ko 13.

$$\frac{\mathrm{d}}{\mathrm{d}k}(\frac{1}{2}\times 13\times \frac{6}{k})$$

Whakareatia te \frac{1}{2} ki te 13, ka \frac{13}{2}.

$$\frac{\mathrm{d}}{\mathrm{d}k}(\frac{13}{2}\times \frac{6}{k})$$

Me whakarea te \frac{13}{2} ki te \frac{6}{k} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{\mathrm{d}}{\mathrm{d}k}(\frac{13\times 6}{2k})$$

Me whakakore tahi te 2 i te taurunga me te tauraro.

$$\frac{\mathrm{d}}{\mathrm{d}k}(\frac{3\times 13}{k})$$

Whakareatia te 3 ki te 13, ka 39.

$$\frac{\mathrm{d}}{\mathrm{d}k}(\frac{39}{k})$$

Ko te pārōnaki o ax^{n} ko nax^{n-1}.

$$-39k^{-1-1}$$

Tango 1 mai i -1.

$$-39k^{-2}$$
