what is Euler's formula Related: RD Sharma Solutions - Ex-19.1 & 19.2...
Euler's formula is a mathematical equation that relates the exponential function, the trigonometric functions, and the imaginary unit. It states that for any real number x,

e^(ix) = cos(x) + i*sin(x)

where e is the base of the natural logarithm, i is the imaginary unit (defined as the square root of -1), cos(x) represents the cosine function, and sin(x) represents the sine function.

This formula is named after the Swiss mathematician Leonhard Euler, who discovered it in the 18th century. It is widely used in various branches of mathematics, physics, and engineering, particularly in complex analysis and Fourier analysis. It provides a powerful link between exponential, trigonometric, and complex numbers, allowing for simplification and manipulation of mathematical expressions.
