NCERT Solutions Class 11 Maths Chapter 5 Exercise 5.2 Question 1: Find the modulus and argument of the complex number Solution: Let and On squaring and adding, we obtain Therefore, Modulus Hence, and and Since both the values of and are negative in III quadrant, Argument Thus, the modulus and argument of the complex number are 2 and respectively. Question 2: Find the modulus and argument of the complex number Solution: Let and On squaring and adding, we obtain Therefore, Modulus Hence, and and Since, lies in the quadrant II, Thus, the modulus and argument of the complex number are 2 and respectively. Question 3: Convert the given complex number in polar form: Solution: Let and On squaring and adding, we obtain Therefore, and and Since, lies in the quadrant IV, Hence, Thus, this is the required polar form. Question 4: Convert the given complex number in polar form: Solution: Let and On squaring and adding, we obtain Therefore, and and Since, lies in the quadrant II, Hence, Thus, this is the required polar form. Question 5: Convert the given complex number in polar form: Solution: Let and On squaring and adding, we obtain Therefore, and and Since, lies in the quadrant III, Hence, Thus, this is the required polar form. Question 6: Convert the given complex number in polar form: Solution: Let and On squaring and adding, we obtain Therefore, and and Since the lies in the quadrant II, Hence, Thus, this is the required polar form. Question 7: Convert the given complex number in polar form: Solution: Let and On squaring and adding, we obtain Therefore, and and Since, lies in quadrant I, Hence, Thus, this is the required polar form. Question 8: Convert the given complex number in polar form: Solution: Let and On squaring and adding, we obtain Therefore, and Since, lies in quadrant I, Hence, Thus, this is the required polar form.
