NO SILLY ANSWERS PLEASE <br> Can someone help me with this?
marusya05 [52]
Keep in mind that, when the logarithm base is not explicitly written, base 10 is assumed, therefore,

\bf \textit{Logarithm Cancellation Rules}\\\\&#10;log_a a^x\implies x\qquad \qquad a^{log_ax}=x\\\\&#10;-------------------------------\\\\&#10;10^{log(3)}+log(100)\implies 10^{log_{10}(3)}+log_{10}(100)\implies 3+log_{10}(10^2)&#10;\\\\\\&#10;3+2\implies 5

Consider the tangent line to the curve y = 6 sin(x) at the point (π/6, 3). (a) Find a unit vector that is parallel to the tangen
mojhsa [17]

Answer:

y=\frac{\pi }{6}+5.196(x-3)

Step-by-step explanation:

We have given the equation y = 6 sin (x)

On differentiating both side \frac{dy}{dx}=m=6cosx

As it passes through the point (\frac{\pi }{6},3)

So \frac{dy}{dx}=6cos\frac{\pi }{6}=5.196

Now the unit vector is parallel to the tangent so m will be 5.196

This passes through the point (\frac{\pi }{6},3)

So unit vector will be y-\frac{\pi }{6}=5.196(x-3)

y=\frac{\pi }{6}+5.196(x-3)
