## Haha yes it is, but it's not undefined, theta is a variable for the vector shown above, so it would not equal to 1 – Nikolaj Mar 28 '13 at 9:40 Add a comment | 2 Answers 2

### From any of the definitions of the exponential function it can be shown that the derivative of e ix is ie ix. Therefore, differentiating both sides gives Therefore, differentiating both sides gives i e i x = ( cos ⁡ θ + i sin ⁡ θ ) d r d x + r ( − sin ⁡ θ + i cos ⁡ θ ) d θ d x . {\displaystyle ie^{ix}=(\cos \theta +i\sin \theta ){\frac {dr}{dx}}+r(-\sin \theta +i\cos \theta ){\frac {d\theta }{dx}}.} translatedPoint = d*[cos(theta); sin(theta)]+[x;y];. 1 Comment.

$e^{i\theta} = cos(\theta) + isin(\theta)$ Does that make sense? It certainly didn't to me when I first saw it. What does it really mean to raise a number to an imaginary power? I think our instinct when reasoning about exponents is to imagine multiplying the base by itself "exponent" number of times.

You also can use the character j as the imaginary unit. To create a complex number without using i and j, use the complex function. May 21, 2020 · A circle with a radius of 10 units is drawn or plotted. Hours are marked from 1 to 12, 30° apart. First, the numbers are converted to string format by using an inbuilt function in MATLAB, i.e. ‘num2str’ and then by using inbuilt ‘text’ function in MATLAB 1 to 12 is written as text in the plot.
