(b) What is the slope of the secant line which intersects the graph at the points (1, −2) and (1 + ∆x, f (1 + ∆x))?
(c) By takinga limit as ∆ x → 0, calculate the slope of the tangent line through (1,-2) as the limit of the slope of the secant line and find the equation for this line.
(a) On the axes below, sketch the functions f (θ) = sin(θ) and g(θ) = 2sin(θ) for 0 ≤ θ ≤ 2 π.
