4 days ago · The argument 𝜃 of a complex number is, by convention, given in the range − 𝜋 < 𝜃 ≤ 𝜋. However, we can also discuss a complex number with an argument greater than 𝜋 or less than − 𝜋. The argument of a complex number within the range ] − 𝜋, 𝜋] is called the principal argument.
Determine the area of the region in the first quadrant (i.e., where 𝑥≥0x≥0 and 𝑦≥0y≥0) that is bounded by the curve y = sqrt (x), the x-axis, and the line y=x-2. I have come to the conclusion that x=4 and x=1 but 1 is a false root, so really x=4. But I am having a problem with the integration part which should give 10/3 as a final ...

Describe the traces of the hyperboloid of one sheet given by equation x2 32 + y2 22 − z2 52 = 1. x 2 3 2 + y 2 2 2 − z 2 5 2 = 1. Hint.
5 days ago · Graph basics. There are certain descriptions which are often used when we talk about graphs. means that the y-values of the graph are positive. means that the y-values of the graph are negative. means that as we move from left to right the y -values on the graph climb. means that as we move from left to right the y -values on the graph drop.
6 days ago · Definition: Exponential Functions. A function of the form 𝑓 ( 𝑥) = 𝑏, where 𝑏 ∈ ℝ > 0 and 𝑏 ≠ 1, is an exponential function. 𝑏 is called the base of the exponential function, and the domain, that is, the set of possible 𝑥 -values, is the real numbers, ℝ.
