Eliminate the parameter in the equations x=cos(t)-5 and y=3sin(t)+6. How can the rectangular equation be described? 1) circle
2) ellipse
3) parabola
4) hyperbola

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.

practice. practice. practice.
