Steps for How to Convert Complex Numbers from Polar to Rectangular Form Step 1: Evaluate the trigonometric functions within the polar form of the complex number. The polar form is of the form {eq}r(\cos\alpha + i\sin\beta) {/eq}. The values of {eq}\cos\alpha {/eq} and {...
Use the formulas in Step 2 to convert the rectangular equation 3x-2y=7 into polar form. Try this example to learn how the process works. Step 4 Substitute x= rcos θ and y=rsin θ into the equation 3x-2y=7 to get (3 rcos θ- 2 rsin θ)=7. ...

It might help to remember that cotangent is defined as cos(x)/sin(x), and since sin(nπ) = 0 for any integer n. This leads to division by zero at these points. 7.1 Troubleshooting the error value When you encounter an error value in a cell a warning symbol appears, displayed in th...
Step 4:Given a complex number in the form {eq}z = r(\cos(\theta) + i\sin(\theta)) {/eq}, we can convert to rectangular form by first evaluating the trigonometric functions. Step 5:Then, distribute the {eq}r {/eq} term into the parenthesis and simplify. ...
How to Make Zongzi(cos2α)/(2sinα-cos^2α) Zongzi is often called "the Chinese tamale" because it is wrapped in bamboo or reed leaves.Inside the zongzi are glutinous rice(江米) and fillings. ①Prepare the glutinous rice and fillings. ②Boil the bamboo leaves.Let them cool and p...
We can use these properties to create the graph of y = cos(x). Let's first take a look at the properties of the cosine function. The domain (which includes the x-values we can plug into y = cos(x) and have a defined function) of y = cos(x) is all real numbers. The ...
