Q
Q: If z = 2e^(iπ/4), then z^2 is?
Solution:
z^2 = (2e^(iπ/4))^2 = 4e^(iπ/2).
Steps: 6
Show Steps
Step 1: Start with the given value of z, which is z = 2e^(iπ/4).
Step 2: To find z^2, we need to square the entire expression: z^2 = (2e^(iπ/4))^2.
Step 3: When squaring a product, we can square each part separately: (2^2) * (e^(iπ/4))^2.
Step 4: Calculate 2^2, which equals 4.
Step 5: Now, calculate (e^(iπ/4))^2. When you square an exponent, you multiply the exponent by 2: e^(iπ/4 * 2) = e^(iπ/2).
Step 6: Combine the results from Step 4 and Step 5: z^2 = 4 * e^(iπ/2).
