SA1-page3

SA1-page3  contains the remaing questions of KVS Mathematics SA - 1

29) P and Q are respectively points on the AB and AC of \(\Delta ABC \). If AP =2 cm, PB=4cm, AQ= 3cm and QC =6 cm, prove that BC = 3 PQ.

30) The median of the following data is 52.5 . find the value x and y, if total frequency = 100.

31) Draw less than cumulative frequency curve and hence find the median .

32) Prove that \(\frac{1 + Cos \theta - Sin^{2} \theta}{Sin \theta (1+Cos \theta )} = Cot \theta \).

33) Evaluate \( \frac{Sin^{2}54^{\circ} -Cos^{2}36^{\circ}}{Cosec^{2}57^{\circ} - Tan^{2} 33^{\circ}} +2 Sin^{2}38^{\circ}Sec^{2}52^{\circ} -Sin^{2}45^{\circ}\).

34) Prove that \( (Sin \theta + Cosec \theta )^{2} + (Cos \theta + Sec \theta)^{2} =7+ Tan^{2}\theta + Cot^{2} \theta   \).
