Two complex numbers z 1 = a 1 + ib 1 & z 2 = a 2 + ib 2 are equal if and only if their real and imaginary parts are equal respectively i.e. ‘a’ is called as real part of z which is denoted by (Re z) and ‘b’ is called as imaginary part of z which is denoted by (Im z). z > 0, 4 + 2i < 2 + 4 i are meaningless. 1. i^ {n} = i, if n = 4a+1, i.e. We can consider a complex number as having the form a + bi where a and b are real number and i, which is called the imaginary unit, has the property that i2 = – 1. JEE Problems (Part 2) 40 min. The basic formulas of Trigonometry are no doubt one of the essential to study topics in mathematics.Considering its importance, in exams such as JEE Main / JEE Advanced there are about 4-5 questions asked directly from the topic alongside some questions in which trigonometry is imbibed into questions asked from some other topic. If OP = |z| = r and arg(z) = θ, then obviously z = r(cosθ + isinθ), called the polar form of z. Also find Mathematics coaching class for various competitive exams and classes.
