Suppose y=arctan(2x) represents our happiness at in-comex, wherexis in hundreds of thousands of dollars (for example, x = 1means income = $100,000). Use differentials to estimate our change in happi-ness when we receive a raise of $10,000 in the following scenarios: our currentincome is a) $25,000, b) $50,000, c)$500,000. Hint: Use ∆x=dx, ∆y≈dy(change in happiness is ∆y).

Length of arc CE = 3.14 units (Approx.)

Step-by-step explanation:

Given:

∠CDE = 60

CD = 3 units

Find:

Length of arc CE

Computation:

Length of arc = [θ/360][2πr]

Length of arc CE = [60/360][2(22/7)(3)]

Length of arc CE = 3.14 units (Approx.)
