multivariable calculus - How do I solve a partial derivative $f(x,y ...
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. 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 … kfc gold wrapper
