WebHigh school mathematics video #artuition WebAug 30, 2016 · The linear approximation formula says that f ( x + Δ x) ≈ f ( x) + f ′ ( x) Δ x. Let y = f ( x) = tan x. Set x = 0 and Δ x = 2 ∘ = π 90 radians. i.e., tan 2 ∘ ≈ π 90 ≈ 0.0349. Note that we can exclude the approximation of π 90 which would require a calculator. Nice work...I was thinking of using approximating formula to ... WebNov 5, 2015 · Using the unit circle we can see that tan (1)= pi/4. Since the "Odds and Evens Identity" states that tan (-x) = -tan (x). Tan (-1)= -pi/4. Knowing that tan is negative in quadrants 2 and 4. the answer is in either of those two quadrants. BUT!!! since inverse of tan is restricted to quadrants 1 and 4 we are left with the only answer -pi/4. エスロン-テープ
