Three nonzero a,b,c are in GP if `b^2=ac`.

Given that three numbers a,b,c are in G.P.If b^2=ac Prove that cot^2 30^@ , cot^2 45^@ , cot^2 60^@ are in G.P.

If a,b,c are in GP then b^(2) = …….

"If the numbers "a,b,c" are in "A.P," then "2b=a+c" .If the numbers "a,b,c" are in G.P,then "b^(2)=ac" If "sin A,cos A,tan A" are in "GP" then "cot^(6)A-cot^(2)A=

Three distinct numbers a,b,c from a GP in that order and the numbers a-:b,b-:c,c-:a form an AP in that order.Then the common ratio of the GP is :

Three numbers a, b, c are lies between 2 and 18 such that their sum is 25. 2, a, b, are in A.P, and b, c, 18 are in G.P. Then abc =

Three distinct numbers a, b, c form a GP in that order and the numbers a+b, b+c, c+a form an AP in that order. Then the common ratio of the GP is

Three numbers a,b, c are between 2 and 18 such that a + b+ c= 25 . If 2,a,b are in A.P and b,c 18 are in G.P then these numbers are…….

If the straight line a x+c y=2b , where a , b , c >0, makes a triangle of area 2 sq. units with the coordinate axes, then a , b , c are in GP a, -b; c are in GP a ,2b ,c are in GP (d) a ,-2b ,c are in GP
