Use differentials (or equivalently, a linear approximation) to approximate sin(26∘) as follows: Let f(x)=sin(x) and find the equation of the tangent line to f(x) at a "nice" point near 26∘. Then use this to approximate sin(26∘).

answer: i don't understand. what are the options

step-by-step explanation:

step-by-step explanation:

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
