This problem is a very simple example of a differential equation: an equation that relates a function to one or more of its deri

omeli [17]

Answer:

f(x) = 1/x

Step-by-step explanation:

The corrected question is:

Suppose f is the function that satisfies

f'(x)= - f²(x)

for all x in its domain, and

f(1) = 1

f(x)= ?

Given:

f'(x) = -(f(x))²

This can be written as:

df/dx = -f²

The equation becomes:

-df/f² = dx

Integrating the above equation on both sides we get:

1/f = x + c where c is constant

f(x) = 1/(x+c)

Now given that:

f(1) = 1

Solving this for c we get:

f(1) = 1 = 1/(1 + c)

1 = 1/ 1+c

1 = 1 + c

c = 1 - 1

c = 0

Now put this value of c in f(x) = 1/(x+c)

f(x) = 1/(x+0)

f(x) = 1/(x)

f(x) = 1/x

Hence

f(x) = 1/x

1. Determine the set of each of the following equations for 0° ≤ x 360° or 0° ≤ t ≤ 360°

soldi70 [24.7K]

Answer:

a).

$\sin(2x) = \frac{1}{2 \sqrt{2} } \\ \\ 2x = { \sin }^{ - 1} ( \frac{1}{2 \sqrt{2} } ) \\ \\ 2x = 45 \degree$

since sine is in the 2nd quadrant, other angle = 180° - x:

$2x = 45 \degree, \: 135 \degree$

we must make two rotations since it's a double angle:

$2x = 45 \degree, \: 135\degree, \: 225\degree, \: 315\degree, \: 495\degree, \: 675\degree \\$

divide each angle by 2:

$x = 22.5\degree, \: 67.5\degree, \: 112.5\degree, \: 157.5\degree, \: 247.5\degree, \: 337.5\degree \\$

Answer = {x: x = 22.5°, 67.5°, 112.5°, 157.5°, 247.5, 337.5°}

b).

$\sin(3z) = - 0.42 \\ 3z = { \sin }^{ - 1} ( - 0.42)$

since ans is negative, we take the quadrants of cosine and tangent:

$3z = 204.8\degree, \: 335.2\degree$

we make three rotations:

$3z = 384.8\degree, \: 515.2\degree, \: 695.2\degree, \: 875.2\degree, \: 1055.2\degree, \\$

answer is {z : z = 128.3°, 171.7°, 231.7°, 291.7°, 351.7°}
