Find the exact value of tan (arcsin (2/

i'm pretty sure it's 477,585,296, but perhaps my math is incorrect.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
