If a Delta b=a-b=5 find (-7)Delta3

If, in Delta ABC, a = 2b and A = 3B, then A :

As is known, the result of an experiment is calculated by performing mathematical operation (like addition, subtraction, multiplication, division, etc.) on several measurements, which have different degrees of accuracy. It has been established that (a) When x= a+b , Delta x = +- (Delta a + Delta b) (b) When x= a -b , Delta x = +- (Delta a + Deltab) (c ) When x = axxb , (Deltax)/(x) = +- ((Deltaa)/(a) +(Deltab)/(b)) (d) When x = (a)/(b) , (Deltax)/(x) = +-((Deltaa)/(a) + (Deltab)/(b)) Read the above paragraph and answer the following questions : (i) Why is absolute error in x = (a -b) , sun of the absolute error in a and b ? (ii) Why is fractional error in x=(a)/(b) , sun of fractional error in a and b ? (iii) What do you learn from this ?

If A, B and C are three non-empty sets such that n(A nn B nn C) = 10 and n(A DeltaB) = n(B Delta C) = n(C Delta A) = 60 , then find the number of elements in A uu B uu C .

Let a,b>0 and Delta=|(-x,a,b),(b,-x,a),(a,b,-x)| then (1) a+b-x is a factor of Delta 2) x^2+(a+b)x+a^2+b^2-ab is a factor of Delta (3) Delta=0 has three real roots if a=b 4) all of these

Delta_(1) and Delta_(2) are respectively areas of in circle and circumcircle of triangle formed by (0,0), (2,0) and (1,sqrt(3)) then which of following is NOT correct (A) Delta_(1)+Delta_(2)=(5 pi)/(3) (B) |Delta_(1)-Delta_(2)|=pi (C) 3Delta_(1)+6Delta_(2)=9 pi (D) [2Delta_(1)+3Delta_(2)]=12 , where [.] is G.I.F.

If Delta_1=|(1,0),(a,b)| and Delta_2=|(1,0),(c,d)| , then Delta_2Delta_1 is equal to :

In Delta ABC , a= 6 ,b=3 and cos (A-B) = 4/5 .Then are of triangle is

In Delta ABC, if a=2b and A=3B, then the value of (c)/(b) is equal to
