Can someone please help me with this....differentiate,, y=(cos(x)^x
N76 [4]
y=\cos^xx=e^{\ln\cos^xx}=e^{x\ln\cos x}

Now differentiate, applying the chain rule on the right hand side.

\dfrac{\mathrm dy}{\mathrm dx}=e^{x\ln\cos x}\dfrac{\mathrm d}{\mathrm dx}[x\ln\cos x]
\dfrac{\mathrm dy}{\mathrm dx}=e^{x\ln\cos x}\left(\ln\cos x-\dfrac{x\sin x}{\cos x}\right)
\dfrac{\mathrm dy}{\mathrm dx}=e^{x\ln\cos x}\left(\ln\cos x-x\tan x\right)
\dfrac{\mathrm dy}{\mathrm dx}=\cos^xx\left(\ln\cos x-x\tan x\right)

Igualacion. <br><br>x-y=3. 2x-3y=4​
Delicious77 [7]

Answer:

x - y = 3

2x - 3y = 4

Igualación

Despejamos una de las incógnitas en cada ecuación e igualamos. (En este caso la x)

3y + 4

x = y + 3 x = ---------------

2

3y + 4

y + 3 = ---------------

2

2 (y + 3 ) = 3y + 4

2y + 6 = 3y + 4

se pasan las incógnitas a un lado y lo que cambia de lado se cambia de signo

3y - 2y = 6 - 4 ⇒ y = 2

sustituimos el valor de y en cualquiera de las dos para obtener el valor de x

x - 2 = 3 ⇒ x = 5

Solución

x = 5

y =2
