What is a formula of cylinder?

The formula for the volume of a cylinder is V=Bh or V=πr2h . The radius of the cylinder is 8 cm and the height is 15 cm. Therefore, the volume of the cylinder is about 3016 cubic centimeters.

What is ellipse equation?

An ellipse is the locus of a point whose sum of the distances from two fixed points is a constant value. The two fixed points are called the foci of the ellipse, and the equation of the ellipse is x2a2+y2b2=1 x 2 a 2 + y 2 b 2 = 1 .

#### What is standard polar equation of line?

Polar or Distance Form of a Straight Line Equation. Q(x,y)≡(h+rcosθ,k+rsinθ).

#### How do you find the polar of a zero equation?

Finding Zeros and Maxima. To find the zeros of a polar equation, we solve for the values of θ that result in r = 0 \displaystyle r=0 r=0. Recall that, to find the zeros of polynomial functions, we set the equation equal to zero and then solve for x.

How do you convert rectangular form to polar form without a calculator?

Converting from Polar Form to Rectangular Form To convert from polar to rectangular, find the real component by multiplying the polar magnitude by the cosine of the angle, and the imaginary component by multiplying the polar magnitude by the sine of the angle.

What is the polar coordinate equation?

Graphing in Polar Coordinates. A typical polar equation is in the form r = f (θ), where f is some function ( of θ). θ is the independent variable, and r is the dependent variable.

## How do you convert rectangular to polar coordinates?

To convert from rectangular coordinates (x,y) to polar coordinates (r, θ), the following equations should be used: r = sqrt( x^2 + y^2) θ = tan^-1 (y/x) Substituting (-3,3) accordingly to the equations, we obtain r equal to 3*sqrt(2) and θ equal to -π/4. Thus, the polar coordinates equivalent to (-3,3) is (3*sqrt(2), -π/4).

## How do you find the polar coordinates of a point?

To find the polar coordinates of a given point, you first have to draw a line joining it with the pole. Then, the point’s coordinates are the length of this line r and the angle θ it makes with the polar axis.

What is a polar graph?

A Polar Graph is one where a set of all points with a given radius and angle that satisfy a Polar Equation, and there are five basic Polar Graphs: And there are two ways to graph/sketch Polar Graphs, either by using Transformations or the Traditional Approach which involves a Table of Values.
