Description: A diagram illustrating Euler's formula (e^iφ = cos φ + i sin φ) on a complex plane with a unit circle. It shows the real (Re) and imaginary (Im) axes, a point P on the circle, and the angle φ, with labels '0', 'cos φ', and 'sin φ'. Below the diagram is Euler's identity: e^(iπ) + 1 = 0.
Description: A diagram illustrating a unit circle on a complex plane with real and imaginary axes. It features vectors, trigonometric functions (cos φ, sin φ), and mathematical notations including 'ρ', 'ō = e^iφ', and 'e^N(ip) + 1 = 0'. The diagram is presented in white on a black background.
Description: A black background features a white unit circle with yellow axes and angle indicators. Text labels include 'Unit Circle', 'y', 'x', 'rad', 'c', 'h', and various degree measurements such as '230°', '220°', '260°', '250°', '240°', '340°', '120°', and markings for '0', '-1', '1', '2', '3', '5', and '-c', '-10°'. Several yellow dots mark points on the circle with corresponding degree values.
Description: The Junkers JU-87 Stuka, renowned for its distinctive inverted gull wings and ominous dive-bombing capabilities, was a German dive bomber and ground-attack aircraft used extensively during World War II. It played a significant role in early German victories, notably during the Blitzkrieg campaigns.
