(1) 2 (2) -1 (3) 0 (4) 163. If coshα = sec x then tan 2 x/2 is :(1) cos2 (α/2) (2) sin2 α/2 (3) cot2 (α/2) (4) tan h2 α/264. The real part of the principle value of 2 -i is :(1) sin (log 2) (2) cos (1/log2) (3) cos [log (1/2)] (4) cos (log2)65. The two vertices of triangle are (2, - 1), (3, 2) and the third vertex lies on x + y = 5. The areaof the triangle is 4 units then the third vertex is :(1) (0,5) or (1,4) (2) (5, 0) or (4, 1) (3) (5, 0) or (1, 4) (4) (0, 5) or (4, 1)66. If 2 a+ b + 3c = 0 than the line ax + by + c = 0 passes through the fixed point that is:(1) 2 , 1 (2) 0, 1 (3) 2 , 0 (4) none of these3 3 3 367. Straight lines ax ± by ± c = 0 represent a :(1) Rhombus (2) Square (3) Rectangle (4) None of these68. The equation of the circle passing through (2a, 0) and whose radical axis w.r.t. the circle x 2 +y 2 = a 2 is x = a will be :2(1) x 2 +y 2 +2ay=0(2) x 2 +y 2 +2ax=0(3) x 2 +y 2 -2ay=0(4) x 2 +y 2 -2ax=069. The circles x 2 +y 2 +2ax+c=0 and x 2 +y 2 +2by+c=0 touches each other then:(1) a 2 +b 2 =c2 (2) 1 + 1 = 1 (3) 1 + a = 1 (4) 1 - 1 = 1a 2 b 2 c 2 a 2 b 2 c a 2 b 2 c70. The pole of the polar w.r.t. the circle x 2 +y 2 = c 2 lies on x 2 +y 2 = 9c 2 then this polar is tangent toconcentric circle whose equation will be :(1) x 2 +y 2 = 4c 2 (2) x 2 +y 2 = c 2 (3) x 2 +y 2 = 9c 2 (4) none of these9 471. In a G.P. (m + n) th the term is a and (m-n) th term is 4 then mth term will be :(1) -6 (2) 1/6 (3) 6 (4) none of these72. The sum of n terms of 1 + 3 + 7 + 15 + … is :
