Too many points for such a simple explanation :)) Whatever:
To get 1/4 of a number you multiply the number by 1/4. Same for any non-percent number. If the number is a percent, say, 23,5%, you first divide it by 100 to get a non-percent, then do the same, that is, multiply it by the number.
Our result is
Answer:
Step-by-step explanation:
2x^3y and 2yx are not like terms since x^3 can't be added to x since it's not x^3 but x^2.
This would be a lot easier with the figure.
Four equal spaces means quarters.
A is 1 mark to the left of 0, so 1/4 to the left of 0. That's -1/4
Answer: Negative one-fourth

dy / dx = sin x / cos y
We rewrite the equation:
(cos (y) * dy) = (sin (x) * dx)
We integrate both sides of the equation:
sin (y) = - cos (x) + C
We use the initial condition to find the constant C:
sin (3pi / 2) = - cos (0) + C
-1 = -1 + C
C = -1 + 1
C = 0
The equation is then:
sin (y) = - cos (x)
Clearing y:
y = Arcosine (-cos (x))
Answer:
An equation for and in terms of x is:
y = Arcosine (-cos (x))
