This will be easier to write, and a lot easier to read, if we temporarily
use another symbol ... say, 'Q' ... to represent ' sin(2x) ' .
Here we go:
Original equation: Q² - 0.5 Q = 0
Factor the left side: Q (Q - 0.5) = 0
This equation is true if either factor is zero:
-- If Q=0, then sin(2x) = 0
2x = 0°, 180°, 360°
x = 0°, 90°, 180°
-- If (Q-0.5) = 0, then Q = 0.5
sin(2x) = 0.5
2x = 30°, 150°
x = 15°, 75°
The whole collection of solutions
between 0° and 360° :
x = 0°, 15°, 75°, 90°, 180° .
3 +dy/dx = 0+ 2x²ydy/dx + 2xy²
dy/dx - 2x²ydy/dx = 2xy² -3
(1 - 2x²y) dy/dx = (2xy²-3)/(1-2x²y)
A) 1/4 of the paint is made with read so that's 25 percent
B) yellow to red paint ratio is 3:1
please crown me if this helped you!<span> </span>
I know these numbers from a triangle because 24+30=54 and 6square root 43 is about 39
If the object moves 170 meters in 20 seconds. There are 60 seconds in a minute. You have to multiply the 170 by 3. One minute it moves 510 meters
