Example Question #11 :Derivatives Of Polar Form

Find the derivative of the following function:

$r=3\cos(\theta)+\theta^2$

Possible Answers:

$\frac{(-3\sin(\theta)+2\theta)\sin(\theta)+(3\cos(\theta)+\theta^2)(\cos(\theta))}{(-3\sin(\theta)+2\theta)(\cos(\theta))-(3\cos(\theta)+\theta^2)(\sin(\theta))}$

$\frac{(-3\sin(\theta)+2\theta)\sin(\theta)-(3\cos(\theta)+\theta^2)(\cos(\theta))}{(-3\sin(\theta)+2\theta)(\cos(\theta))-(3\cos(\theta)+\theta^2)(\sin(\theta))}$

$\frac{(-3\sin(\theta)+2\theta)\sin(\theta)-(3\cos(\theta)+\theta^2)(\cos(\theta))}{(-3\sin(\theta)+2\theta)(\cos(\theta))+(3\cos(\theta)-\theta^2)(\sin(\theta))}$

$\frac{(-3\sin(\theta)+2\theta)\cos(\theta)+(3\cos(\theta)+\theta^2)(\cos(\theta))}{(-3\sin(\theta)+2\theta)(\sin(\theta))-(3\cos(\theta)+\theta^2)(\sin(\theta))}$

Correct answer:

$\frac{(-3\sin(\theta)+2\theta)\sin(\theta)+(3\cos(\theta)+\theta^2)(\cos(\theta))}{(-3\sin(\theta)+2\theta)(\cos(\theta))-(3\cos(\theta)+\theta^2)(\sin(\theta))}$

解释:

The derivative of a polar function is given by

$\frac{\mathrm{dy} }{\mathrm{d} x}=\frac{\frac{dr}{d\theta}\sin(\theta)+r\cos(\theta)}{\frac{dr}{d\theta}\cos(\theta)-r\sin(\theta)}$

First, we must find the derivative of the function, r:

$\frac{dr}{d\theta}=-3\sin(\theta)+2\theta$

We used the following rules to find the derivative:

$\frac{\mathrm{d} }{\mathrm{d} x} \cos(\theta)=-\sin(\theta)$ , $\frac{\mathrm{d} }{\mathrm{d} x}x^n=nx^{n-1}$

Now, plug in the derivative and the original function r into the above formula:

$\frac{(-3\sin(\theta)+2\theta)\sin(\theta)+(3\cos(\theta)+\theta^2)(\cos(\theta))}{(-3\sin(\theta)+2\theta)(\cos(\theta))-(3\cos(\theta)+\theta^2)(\sin(\theta))}$

Example Question #12 :Derivatives Of Polar Form

Find the derivative of the following function:

$r=\theta+\tan(\theta)$

Possible Answers:

$\frac{(1+\sec^2(\theta))\cos(\theta)+(\theta+\tan(\theta))\sin(\theta)}{(1+\sec^2(\theta))\cos(\theta)-(\theta+\tan(\theta))\sin(\theta)}$

$\frac{(1+\sec^2(\theta))\sin(\theta)+(\theta+\tan(\theta))\cos(\theta)}{(1+\sec^2(\theta))\cos(\theta)+(\theta+\tan(\theta))\sin(\theta)}$

$\frac{(1+\sec^2(\theta))\sin(\theta)+(\theta+\tan(\theta))\cos(\theta)}{(1+\sec^2(\theta))\cos(\theta)-(\theta+\tan(\theta))\sin(\theta)}$

$\frac{(1+\sec^2(\theta))\sin(\theta)-(\theta+\tan(\theta))\cos(\theta)}{(1+\sec^2(\theta))\cos(\theta)-(\theta+\tan(\theta))\sin(\theta)}$

Correct answer:

$\frac{(1+\sec^2(\theta))\sin(\theta)+(\theta+\tan(\theta))\cos(\theta)}{(1+\sec^2(\theta))\cos(\theta)-(\theta+\tan(\theta))\sin(\theta)}$

解释:

The derivative (slope of the tangent line) of a polar function is given by the following formula:

$\frac{\mathrm{dy} }{\mathrm{d} x}=\frac{\frac{dr}{d\theta}\sin(\theta)+r\cos(\theta)}{\frac{dr}{d\theta}\cos(\theta)-r\sin(\theta)}$

So, we must simply find $\frac{dr}{d\theta}$ and plug it into the above formula:

$\frac{dr}{d\theta}=1+\sec^2(\theta)$

The following rules were used to find the derivative:

$\frac{\mathrm{d} }{\mathrm{d} x} x^n=nx^{^{n-1}}$ , $\frac{\mathrm{d} }{\mathrm{d} x} \tan(x)=\sec^2(x)$

Now, plug the given function and its derivative into the above formula to get our answer:

$\frac{(1+\sec^2(\theta))\sin(\theta)+(\theta+\tan(\theta))\cos(\theta)}{(1+\sec^2(\theta))\cos(\theta)-(\theta+\tan(\theta))\sin(\theta)}$

What is the derivative of $r=4sin\theta+2$ ?

Possible Answers:

$\frac{8cos\theta\sin\theta-2\cos\theta}{4+8\sin^{2}\theta+2sin\theta}$

$\frac{8cos\theta\sin\theta+2\cos\theta}{4+8\sin^{2}\theta-2sin\theta}$

$\frac{8cos\theta\sin\theta+2\cos\theta}{4-8\sin^{2}\theta-2sin\theta}$

$\frac{8cos\theta\sin\theta+2\cos\theta}{4-8\sin^{2}\theta+2sin\theta}$

$\frac{8cos\theta\sin\theta-2\cos\theta}{4-8\sin^{2}\theta-2sin\theta}$

Correct answer:

$\frac{8cos\theta\sin\theta+2\cos\theta}{4-8\sin^{2}\theta-2sin\theta}$

解释:

In order to find the derivative $\frac{dy}{dx}$ of a polar equation $r=4sin\theta+2$ , we must first find the derivative ofwith respect to $\theta$ 作为follows:

$\frac{dr}{d\theta}=4cos\theta$

We can then swap the given values of $\frac{dr}{d\theta}$ andinto the equation of the derivative of an expression into polar form:

$\frac{dy}{dx}=\frac{\frac{dr}{d\theta}sin\theta+rcos\theta}{\frac{dr}{d\theta}cos\theta-rsin\theta}$

$\frac{dy}{dx}=\frac{4cos\theta\sin\theta+(4sin\theta+2)cos\theta}{4cos\theta\cos\theta-(4sin\theta+2)sin\theta}$

$\frac{dy}{dx}=\frac{4cos\theta\sin\theta+4sin\theta\cos\theta+2\cos\theta}{4cos\theta\cos\theta-4sin\theta\sin\theta-2sin\theta}$

$\frac{dy}{dx}=\frac{8cos\theta\sin\theta+2\cos\theta}{4(cos^{2}\theta-sin^{2}\theta)-2sin\theta}$

Using the trigonometric identity $\sin^{2}\theta+\cos^{2}\theta=1$ , we can deduce that $\cos^{2}\theta=1-\sin^{2}\theta$ . Swapping this into the denominator, we get:

$\frac{dy}{dx}=\frac{8cos\theta\sin\theta+2\cos\theta}{4((1-\sin^{2}\theta)-sin^{2}\theta)-2sin\theta}$

$\frac{dy}{dx}=\frac{8cos\theta\sin\theta+2\cos\theta}{4(1-2\sin^{2}\theta)-2sin\theta}$

$\frac{dy}{dx}=\frac{8cos\theta\sin\theta+2\cos\theta}{4-8\sin^{2}\theta-2sin\theta}$

$\frac{3\cos\theta+10sin\theta\cos\theta}{-5-3\sin\theta}$

Correct answer:

$\frac{3\cos\theta-10sin\theta\cos\theta}{-5-3\sin\theta}$

解释:

In order to find the derivative $\frac{dy}{dx}$ of a polar equation $r=3-5sin\theta$ , we must first find the derivative ofwith respect to $\theta$ 作为follows:

$\frac{dr}{d\theta}=-5cos\theta$

We can then swap the given values of $\frac{dr}{d\theta}$ andinto the equation of the derivative of an expression into polar form:

$\frac{dy}{dx}=\frac{\frac{dr}{d\theta}sin\theta+rcos\theta}{\frac{dr}{d\theta}cos\theta-rsin\theta}$

$\frac{dy}{dx}=\frac{-5cos\theta\sin\theta+(3-5sin\theta)cos\theta}{-5cos\theta\cos\theta-(3-5sin\theta)sin\theta}$

$\frac{dy}{dx}=\frac{-5cos\theta\sin\theta+3\cos\theta-5sin\theta\cos\theta}{-5cos\theta\cos\theta-3\sin\theta+5sin\theta\sin\theta}$

$\frac{dy}{dx}=\frac{3\cos\theta-10sin\theta\cos\theta}{-5(cos^{2}\theta+\sin^{2}\theta)-3\sin\theta}$

Using the trigonometric identity $\sin^{2}\theta+\cos^{2}\theta=1$ , we can simplify the denominator to be

$\frac{dy}{dx}=\frac{3\cos\theta-10sin\theta\cos\theta}{-5-3\sin\theta}$
