Answer:

$\theta=\frac{n\pi}{5}$

Step-by-step explanation:

You have the following function:

$r=2sin5\theta$ (1)

In order to find the zeros of the function you equal to zero the equation (1), and then you solve for θ:

$2sin5\theta=0\\\\sin5\theta=0\\\\5\theta=sin^{-1}(0)=n\pi;\ \ \ \ n=0,1,2,3,..\\\\\theta=\frac{n\pi}{5}$

Then, there are infinite zeros for the function of the equation (1), because n has infinite positive integers values.

Answer:

${ \tt{a - x = y}} \\ \\ { \boxed{ \tt{x = a - y}}}$

${ \tt{m = k - x}} \\ \\ { \boxed{ \tt{x = k - m}}}$

${ \tt{k - {t}^{2}x = m }} \\ { \tt{ {t}^{2} x = k - m}} \\ \\ { \boxed{ \tt{x = \frac{k - m}{ {t}^{2} } }}}$
