FAQs on Trigonometric and Exponential form of Complex Numbers Video Lecture - Mathematical Methods - Physics
| 1. What is the trigonometric form of a complex number? |  |
Ans. The trigonometric form of a complex number is represented as $re^{i\theta}$, where r is the magnitude of the complex number and $\theta$ is the argument.
| 2. How do you convert a complex number from rectangular form to trigonometric form? | |
Ans. To convert a complex number from rectangular form (a + bi) to trigonometric form, we calculate the magnitude r = $\sqrt{a^2 + b^2}$ and the argument $\theta = \tan^{-1}(\frac{b}{a})$. Then, the trigonometric form is $re^{i\theta}$.
| 3. What is the exponential form of a complex number? | |
Ans. The exponential form of a complex number is represented as $re^{i\theta}$, where r is the magnitude of the complex number and $\theta$ is the argument.
| 4. How do you convert a complex number from trigonometric form to exponential form? | |
Ans. To convert a complex number from trigonometric form (re^{i\theta}) to exponential form, we simply write it in the form $re^{i\theta}$.
| 5. What is the relationship between the trigonometric and exponential forms of complex numbers? | |
Ans. The trigonometric form and exponential form of a complex number are equivalent representations of the same number. They provide different ways to express the magnitude and argument of the complex number.
