(B) `(1+sqrt(5))/(2)`
(C) `1+sqrt(5),`
(D) `(1-sqrt(5))/(2)`

The value of cos48cos12 (A) (sqrt(5)+3)/(8) (B) (3-sqrt(5))/(2) (C) (sqrt(5)+1)/(4) (D) (sqrt(5)-1)/(4)

If sin2 theta=cos3 theta and theta is an acute angle,then sin theta equal (a) (sqrt(5)-1)/(4) (b) -((sqrt(5)-1)/(4))( c) (sqrt(5)+1)/(4) (d) (-sqrt(5)-1)/(4)

The length of the tangent of the curve y=x^(2)+2 at (1, 3) is (A) sqrt(5) (B) 3sqrt(5) (C) (3)/(2) (D) (3sqrt(5))/(2)

(sqrt(5)-1)/(sqrt(5)+1)+(sqrt(5)+1)/(sqrt(5)-1)

(1)/(2+sqrt(3))+(2)/(sqrt(5)-sqrt(3))+(1)/(2-sqrt(5))=0
