1. Draw a circle
2. Keeping your compasses open the same distance stick the point on the edge of the circle and draw two little arcs that cut the circle.
3. Stick the point in one the arcs and draw another arc further along the circle. Repeat until you have 6 arcs marked.
4. Use a ruler or straight edge to join up the arcs.

What are the points of inflection of k(x)=sinx-(1/4)sin2x
zalisa [80]

Answer:

Option d is correct.

Step-by-step explanation:

The point of inflection of a function y = f(x) at a pointy c is given by f''(c) = 0.

Now, the given function is

k(x) = \sin x - \frac{1}{4}\sin 2x

Differentiating with respect to x on both sides we get,

k'(x) = \cos x - \frac{1}{2} \cos 2x

Again, differentiating with respect to x on both sides we get,

k''(x) = - \sin x + \sin 2x = - \sin x + 2 \sin x \cos x

So, the condition for point of inflection at point c is

k''(c) = 0 = - sin c + 2 sin c cos c

⇒ sin c(2cos c - 1) = 0

⇒ sin c =  0 or \cos c = \frac{1}{2}

⇒ c = 0 or c = \pm \frac{\pi}{3}

Therefore, option d is correct. (Answer)

How many zeros are in f(x) = 3x^4 + x + 2
lana [24]

Answer:

The power of the polynomial determines the number of zeroes it has in this case power is 4 so 4 zeroes. Whereas in 5^3+4 it has 3 zeroes as its power is 3. U can find the zero by trial and error method.

Hope this helps.
