what is (a+b+c)whole square
sir how to solve quadratic inequalities by wavy curve method
Q Find the square root of the complex number 5 -12i.
if (1-i/1+i)500=a+ib, find the values of a and b
cosA +cosB +cosC +cos(A+B+C) = 4cos((A+B) / 2)cos((B+C) / 2)cos((C+A) / 2)
Find the modulus and argument of 1 + 2 i / 1 - 3 i ???
if the ratio of the roots of the equation x2+px+q=0 is equal to the ratio of the roots of the equation x2+lx+m=0, prove that mp2=ql2
Express in polar form 1 + 2i/1-3i
If (x+iy)^1/3 =(a+ib),prove that (x/a+y/b)=4(a^2-b^2)?
If (x + iy) = sqrt [(1+i)/(1-i)],
prove that : x2 + y2 = 1
if alpha and beta are 2 different complex numbers with |beta| = 1, then find |beta-alpha/1-bar alpha*beta|
If z =(x+iy) and w =( 1 - iz) / (z - 1) such that | w | = 1 then show that z is purely real .
pls solve this question.... if (1+2i)(2+3i)(3+4i)= x+iy.Show that x^2 +y^2 =1625.
if (x+iy)3 = u+iv, then show that u/x +v/y = 4(x2 - y2)
find the value of x and y if (1+i)x-2i/3+i + (2-3i)y+i/3-i =i
If z = x+iy and w = 1 - i2 / z-i
Show that mod w = 1 implies z is purely real.
if z is a complex number and |z|=1 then prove that z-1/z+1 is a purely imaginary number
