1. Which of the following equations is an equation of a cardioid in polar form? y= cosx r= 5 - 5cosθ r= θ sinr= cosθ 2. Which of the following statements is true about the polar equationr= 8 + 8sinθ? This is not an equation of a cardioid. ...
This is a mysterious definition. Why does it produce the envelope? For a fixedtand any the curvesF(x,y,t)=0 andF(x,y,t+h)=0 (that is,CtandCt+h) cross at a point near the envelope. Solving this pair of equations forxandyis equivalent to solvingF(x,y,t)=0 and forxandy.Then...
This is based on both theoretical arguments from the ball movement equations and from the numerical solution of such equations. We found that the vertical deflection fits a cardioid model as function of the Magnus coefficient and the spin angle, for a set of trajectories with initial linear ...
Note that using double integrals in finding the area of the region the formula is A=∫∫rdrdθ which we need to determine the limits for integration based on the given equations. Answer and Explanation: Below is the graph, Graph Let us find the limits, ...
Non-dimensional governing equations (stream-vorticity functions) are solved numerically using the control volume finite element method (CVFEM). The ecological coefficient of performance (ECOP) as a criterion of cavity performance is evaluated. The effects of decision variables such as Darcy number, ...

A cardioid is a plane curve traced by a point on the perimeter of a circle rolling (a circumscribed circle) around a fixed circle (basic circle) of the same diameter (a), and is expressed using Equations (1)–(2). The expanded cardioid given in Equations (3)–(4) is obtained by mu...
