Simplify using Synthetic Division
erma4kov [3.2K]
Step 1
Write down the first coefficient without changes:
−3223−10−3
−3

Step 2
Multiply the entry in the left part of the table by the last entry in the result row (under the horizontal line).
Add the obtained result to the next coefficient of the dividend, and write down the sum.
−3223(−3)⋅2=−63+(−6)=−3−10−3

Step 3
Multiply the entry in the left part of the table by the last entry in the result row (under the horizontal line).
Add the obtained result to the next coefficient of the dividend, and write down the sum.

If θ = 330° and α = 300°, find the exact value of tan θ − sin α.
Vilka [71]
X = tan (330) - sin (330)
x = 0.133557089 - -0.132381629
x = 0.133557089 + 0.132381629
x = 0.265938718
