In a triangle `ABC`, the sides `b,c` are given. If there is an error `deltaA` in measuring angle A.Then side a is error `deltaa` in the side a is

If DeltaABC the sides, b,c are given. If there is an error deltaA in measuring angle 'A' then deltaa=

In a /_\ ABC the sides b and c are given. If there is an error dA in measuring angle A, then the error da in side a is given by

If in Delta ABC the sides a,b,c are in A.P. Then

The area S of a triangle is calculated by measuring the sides b and c, and angleA . If there be an error deltaA in the measurement of angleA , show that the relative error in area is given by (deltaS)/(S) = cot A.deltaA

If in Delta ABC , sides a, b, c are in A.P. then

If in Delta ABC , sides a, b, c are in A.P. then

In a triangle ABC,vertex angles A,B,C and side BC are given .The area of !ABC is

In a triangle ABC,vertex angles A,B,C and side BC are given .The area of triangle ABC is

The area S of a triangle is calculated by measuring b,c and A. If the be an error DeltaA in the measurement of A, show that the relative error in area is given by (DeltaS)/s = cot A. DeltaA
