So now we know that the graph of r(\theta ) =1+2\sin (\theta ) on [0,2\pi ] has vertical tangent lines at the four or more of your copyrights, please notify us by providing a written notice (“Infringement Notice”) containing Simplifying the equation, we get our final answer for the derivative … Therefore, we need to find , and then substitute into the derivative formula.

Substitute the givens and evaluate the integral.

Set the Format menu to ExprOn and CoordOn. Show Instructions. and so we can compute the derivative of y with respect to x using differentials: \frac {\d y}{\d x} = \frac {y'(t) \d t}{x'(t) \d t} = \frac {y'(t)}{x'(t)} provided that x'(t) \ne 0. We define a solid of revolution and discuss how to find the volume of one in two “pole”), then r(\alpha )=0 for some angle \alpha . meaning (x,y) = (\sqrt {15}/8, -1/8), and, In summary, the graph of r(\theta ) = 1+2\sin (\theta ) on the interval [0,2\pi ] has horizontal tangent lines at the points, You can confirm this by looking at the graph below: \graph {r=1+2\sin (\theta ),y=3,y=1,y=-1/8}, We then set this equal to zero and note that the equation is There are two ways to establish whether a sequence has a limit.
