In summary, an intercept in mathematics refers to a point where a line or curve crosses either the x-axis or y-axis on a graph. It can also be referred to as a root or zero. To find the x-intercept of z3=3e^(-ipie/4), one can set z3 equal to 0 and solve for x using the properties of logarithms. The modulus of a complex number, also known as its absolute value or magnitude, is its distance from the origin on the complex plane. To find the modulus of z3=3e^(-ipie/4), the Pythagorean theorem can be used. The angle in the exponential term of z3=3e^(-ipie/

I don't understand how this is supposed to be a function. What is your independent variable..? z..? z3..? z^3..?
 
  • #3
sorry just let z3=z

Recall Euler's formula for that one.

Still, [itex]z=3e^{-i\pi \frac{e}{4}}[/itex] is not a function but some fixed constant number.
 

FAQ: Finding Intercepts & Modulus of z3=3e^(-ipie/4)

What is an intercept in mathematics?

An intercept is a point where a line or curve crosses either the x-axis or the y-axis on a graph. It is also known as a root or a zero.

How do you find the x-intercept of z3=3e^(-ipie/4)?

To find the x-intercept of z3=3e^(-ipie/4), we set z3 equal to 0 and solve for x. This can be done by taking the natural logarithm of both sides and using the properties of logarithms to isolate x.

What is the modulus of a complex number?

The modulus of a complex number is its distance from the origin on the complex plane. It is also known as the absolute value or magnitude of a complex number.

How do you find the modulus of z3=3e^(-ipie/4)?

To find the modulus of z3=3e^(-ipie/4), we use the Pythagorean theorem by taking the square root of the sum of the squares of the real and imaginary parts of the complex number. In this case, the modulus is equal to 3.

What is the significance of the angle in the exponential term of z3=3e^(-ipie/4)?

The angle, -ipie/4, in the exponential term of z3=3e^(-ipie/4) represents the direction and rotation of the complex number on the complex plane. It is also known as the argument or phase angle of the complex number.
