WebVery simple, add up the real parts (without i) and add up the imaginary parts (with i): This is equal to use rule: (a+b i )+ (c+d i) = (a+c) + (b+d) i (1+i) + (6-5i) = 7-4 i 12 + 6-5i = 18-5 i (10-5i) + (-5+5i) = 5 Subtraction Again very simple, subtract the real parts and subtract the imaginary parts (with i): WebWe want to find the sum S ( t) = t + 2 t 2 + 3 t 3 + 4 t 4 + ⋯ + ( n − 1) t n − 1 + n t n. Multiplying both sides by t, we get t S ( t) = t 2 + 2 t 3 + 3 t 4 + 4 t 5 + ⋯ + ( n − 1) t n + n t n + 1. Subtract, and rearrange a bit. We get ( ∗) ( 1 …
WebSo you could say 1 plus 2 plus 3 plus, and you go all the way to plus 9 plus 10. And I clearly could have even written this whole thing out, but you can imagine it becomes a lot harder if you wanted to find the sum of the first 100 numbers. So that would be 1 plus 2 plus 3 plus, and you would go all the way to 99 plus 100. WebAnd now we can do the same thing with this. 3 times n-- we're taking from n equals 1 to 7 of 3 n squared. Doing the same exact thing as we just did in magenta, this is going to be equal to 3 times the sum from n equals 1 to 7 of n squared. We're essentially factoring out the 3. We're factoring out the 2. n squared.

WebHere is what is now called the standard form of a complex number: a + bi. It is the real number a plus the complex number , which is equal to bi. 3 + 2 i. a —that is, 3 in the example—is called the real component (or the real part). b (2 in the example) is called the imaginary component (or the imaginary part).
