Trigonometric ratios are mathematical relationships between the angles and sides of a right-angled triangle. The primary trigonometric ratios are sine, cosine, and tangent, The Trigonometric formulas
sin (? ) = Perpendicular/ Hypotenuse
cos (? ) = Base / Hypotenuse
tan (? ) = Perpendicular / Base
There are several real life applications of trigonometric functions such as in Architecture & Engineering, Astronomy & Navigation, Aviation and Construction.

Students have confusions understanding the difference between the real and imaginary number and how they form complex number. Well here is the simple explaination, Real numbers include all the rational and irrational numbers such as 0, 1,2.78, 9.9999. etc. while imaginary numbers involve i, the square root of –1. A combination of both real and imaginary number forms a complex number. for example; 3 + 4.

Chapter 4 of class 11 Maths covers concepts such as complex numbers, imaginary unit i, algebra of complex numbers, polar representation, quadratic equations, and the nature of roots. Students can find details below;
Definition of Complex Numbers: Introduction to the general form a + ib, where i is the imaginary unit (i² = –1).
Algebra of Complex Numbers: Operations such as addition, subtraction, multiplication, and division of complex numbers.
Complex Plane (Argand Plane): Graphical representation of complex numbers using the x-axis (real part) and y-axis (imaginary part).
Modulus and Conjugate of a Complex Number
Modulus = |z

Complex Numbers are one of the most important topics in Mathematics which extends the concepts of mathematical understanding. Complex number is expressed in the form a + ib, where a and b are real numbers, and i is the imaginary unit, satisfying i² = –1. Complex numbers represent mathematical values that cannot be expressed using only real numbers. Several concepts related to complex numbers such as Argand Plane, Modulus, Conjugate are available in class 11 Maths.
