WebWe conclude that for 0 < θ < ½ π, the quantity sin(θ)/θ is always less than 1 and always greater than cos(θ). Thus, as θ gets closer to 0, sin(θ)/θ is "squeezed" between a ceiling at height 1 and a floor at height cos θ, which rises towards 1; hence sin(θ)/θ must tend to 1 as θ tends to 0 from the positive side: + =. For the case where θ is a small negative … WebH′(θ)= H′′(θ)= [−110 Points] SCALC9 2.4.037 Let the function f be defined by f(x)=sec(x)tan(x)−1 (a) Use the Quotient Rule to differentiate the function f′(x). f′(x)= (b) Simplify the expression for f(x) by writing it in termis of sin(x) and cos(x), and then find f′(x). f′(x)= (c) Show that your answers to parts (a)

WebHere we derive a formula for the arc length of a curve defined in polar coordinates. In rectangular coordinates, the arc length of a parameterized curve ( x ( t), y ( t)) for a ≤ t ≤ b is given by. L = ∫ a b ( d x d t) 2 + ( d y d t) 2 d t. In polar coordinates we define the curve by the equation r = f ( θ), where α ≤ θ ≤ β.
WebIf we can’t get it into one of these, we either use power reduction formulas on sin 2 θ and cos 2 θ; or we write everything in terms of seck(x) where k is odd and work hard. (Try to Use sin 2 θ + cos 2 θ = 1 or tan 2 θ + 1 = sec 2 θ only in the numerator.) If no other clear strategy, put everything in terms of sin θ and cos θ. sanchoteneWeb1 (1 pt).
