Mathematics seems to be a nightmare for majority of students, as they lack confidence and practice of the subject. We at BYJU’S provide students of class 11th with important markwise questions for practice. Practicing these question would definitely provide you an idea about the pattern of examination, and questions that are usually framed in this section. Here we provide few important 6 marks questions for practice. As these questions are little tricky, thus this section require a good practice of different long type questions, which can be framed in the final examination.
Important 6 Marks Questions for Class 11 Maths exam are as follows

Question 3 Show that
\(\frac{1.2^{2} + 2.3^{2} + …….. + n(n+1)^{2}}{1^{2}.2+ 2^{2}.3+ ………+ n^{2}.(n+1)} = \frac{3n+5}{3n+1}\)
Question 4 Describe the set of complex number z such that
\(\left  \frac{z+2i}{z+5+4i} \right  = 5\)
Question 5 A family of 4 members planner to go for Goa by train during summer for adventures. On the day of Journey all the auto/taxi drivers were on strike due to price hike of petrol.
