Write the complex number in trigonometric form, once using degrees and once using radians. Begin by sketching the graph to help find the argument 𝜃. −4 degrees _______ radians ________
Added by Chirag G.
Step 1
The magnitude of a complex number is given by the formula |z| = √(Re(z)^2 + Im(z)^2), where Re(z) is the real part and Im(z) is the imaginary part. In this case, the complex number is -4. Since there is no imaginary part, Im(z) = 0. Therefore, the magnitude is Show more…
