complex number
i = √(-1) and i² = 1 and i³ = 3
*Complex number is denoted by Z = x+iy where "x" is real value(or part) while "y" is imaginary value(or part)
*Inverse of complex number
z–¹ = (conjugate of z/r)

circle
*Circumference of circle = 2πr where r is radius of circle
*Area of circle = πr²
*Length of Arc = (x°/360)×2πr
*Area of sector = (x°/360°)×πr²
*Area of segment = (x°/360°)×πr² -r²SinxCosx
Where x is angle subtended by arc
*Equation of circle :- (x-h)² + (y-k)² = r²
Where coordinate of point on circle is A(x,y) , centre is C(h,k) and radius is "r"
*Area of circle = πr²
*Length of Arc = (x°/360)×2πr
