how would u solve this: 2sin(x)-1=0
exact step to solving would be nice
thanx
Add one to both sides and divinde both sides by 2.
sin x = 1/2
Now look up the angle that has a sine of 1/2. That's the answer
what is a derpeciation expense
The word derpeciation does not exist. You probably mean depreciation. It is a bookkeeping estimate of how much value of an asset is lost because of use, againg, or the extraction of minerals.
To solve the equation 2sin(x) - 1 = 0, you can follow these steps:
1. Add 1 to both sides of the equation:
2sin(x) = 1
2. Divide both sides of the equation by 2:
sin(x) = 1/2
Now, to find the angle that has a sine of 1/2, you can use an inverse trigonometric function, specifically the arcsine (sin⁻¹) function. This function gives you the angle whose sine is the given value.
So, take the arcsine of both sides of the equation:
x = sin⁻¹(1/2)
Using a calculator or reference table, you can find that the angle whose sine is 1/2 is π/6 or 30 degrees. Therefore, the solution to the equation 2sin(x) - 1 = 0 is x = π/6 or x = 30 degrees.
Regarding your second question, depreciation expense is an accounting concept that represents the allocation of the cost of an asset over its useful life. It reflects the decrease in value or worth of an asset due to factors like wear and tear, obsolescence, or the passing of time. Depreciation expense is recorded to recognize the reduction in the asset's value as an expense on the income statement and also to show the reduction in the asset's carrying value on the balance sheet.
