The trigonometric form of the complex number 1 + 3i is 3.16[cos(71.57)° + isin(71.57°)]
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Complex number is in the form z = a + bi, where a, b are real numbers.
Given the complex number z = 1 + 3i
In polar form: r = √(1² + 3²) = 3.16
Ф = tan⁻¹ (3/1) = 71.57⁰
The trigonometric form of the complex number 1 + 3i is 3.16[cos(71.57)° + isin(71.57°)]

Divide by 4
X2=9
Square root of x2 is x and the square root of 9 is 3
X=3
Answer:
Which statements about square roots are true? Check all that apply.
The square root of a positive number cannot be negative.
All positive numbers have two square roots.
StartRoot 18 EndRoot= 9 because 9(2) = 18.
StartRoot 49 EndRoot= 7 because 7(7) = 49.
StartRoot 25 EndRoot = 5 because 52= 25.
